the center of the Sun's disk. It appears that a coronal mass
ejection was launched toward Earth. An interplanetary shock wave
could pass our planet during the next 24 to 48 hours, triggering
moderate geomagnetic activity and aurorae. For more information

Aurora Watch: Skywatchers in northern Europe, Canada, Alaska, and the
northermost tier of US states could be treated to a display of aurora
borealis tonight thanks to elevated levels of geomagnetic activity late in
the day on March 29.
Also today, the SOHO spacecraft captured beautiful images of a full-halo
coronal mass ejection (CME) from the Sun. Full-halo CMEs are massive
bubbles of hot gas headed either directly toward or away from Earth. This
one appears to have erupted on the back side of the Sun and is proceeding
away from our planet.

Propagation Report from ARRL
Geomagnetic indices did rise last Friday, the day before the
contest, but even then the planetary K index rose only briefly to 4.
On Saturday and Sunday the planetary K index was mostly 1 or 2, and
during one period was even 0. What is really interesting is that the
College K index, measured in Alaska where the geomagnetic activity
is higher due to proximity to the polar region, was actually 0 over
six 3 hour periods on Saturday and Sunday.
Solar flux and sunspot numbers were higher this week than last, with
average sunspot numbers up 54 points and average solar flux rising
several points. Solar flux actually peaked for the short term during
the previous week on March 22, when the noon reading at Penticton
was 233.8 and the reading two hours later was 235.6. The low for
week was Tuesday, when solar flux was 200.9. It may go lower this
weekend, if solar flux this Sunday goes below 200.
The predicted solar flux for the next five days, Friday through
Tuesday, is 205, 200, 195, 205 and 210. Flux values may again dip
below 200 around April 10-16, then peak near 250 around April 22 or
23. Possible days of geomagnetic upset, based on the solar rotation
are April 18 and 19 and April 28.
MSNBC ran another story this week on the so-called solar heartbeat.
You can see the article at http://www.msnbc.com/news/389042.asp,
which explains a theory concerning how layers of gas rotating at
different speeds may affect the formation of sunspots and solar
flares. MSNBC also ran a story about a new solar satellite that was
launched last Saturday. Called IMAGE, or Imager for
Magnetosphere-to-Aural Global Exploration, it will be used to study
the relationship between solar wind and the earth's magnetosphere.
It will deploy four wire antennas that are each 820 feet long,
making it the longest artificial object in space. Read about it at
http://www.msnbc.com/news/386647.asp?0a=235A162. NASA also ran a
story on the IMAGE at
http://science.msfc.nasa.gov/headlines/y2000/ast27mar_1m.htm.
Sunspot numbers for March 23 through 29 were 236, 230, 243, 255,
227, 232 and 238 with a mean of 237.3. 10.7 cm flux was 224.1,
218.9, 205.1, 211.3, 204.9, 200.9 and 208.8, with a mean of 210.6,
and estimated planetary A indices were 11, 10, 8, 5, 5, 5 and 9,
with a mean of 7.6.

Space Weather News for April 4-5, 2000
The interplanetary magnetic field in the vicinity of Earth turned southward
on April 4. This condition often creates a weak point in our planet's
magnetospheric shielding against the solar wind. Geomagnetic activity is
currently high. If active conditions continue, observers in northern
Europe, Canada, Alaska and the northern tier of US states could be in for a
display of aurora borealis around local midnight on April 5 (when April 4
turns into April 5). The Moon is just one day past New, meaning that even
very faint Northern Lights could be visible against tonight's dark skies.

Propagation Forecast Bulletin 14
April 7, 2000
The sunspot number took a big leap this week, rising to 301 on
Sunday. It has not been this high since November 12 of last year,
when it was 324. Two days prior on November 10 meters the solar flux
was 343, which is still the record for this cycle. The average
sunspot count for the week was only up about 8 points though, and
average solar flux was about the same as last week.
Solar flux is a measurement of 2.8 GHz energy from the sun, measured
at the Dominion Radio Astrophysical Observatory operated by the
National Research Council Canada in Penticton, British Columbia. You
can visit the observatory web site at http://www.drao.nrc.ca/.
Sunspot numbers are calculated by multiplying the number of visible
sunspot groups by 10, and adding the number of individual spots in
all the groups. A multiplication factor is also used, and it differs
for each observatory. You can see a complete explanation for sunspot
numbers and their derivation at
http://spacescience.com/headlines/y2000/ast05apr_1m.htm.
Geomagnetic indices have been high this week, with the average
planetary A index almost double last week's number. The A index was
in double-digits every day, with April 4 being the most disturbed.
The planetary A index was 21, with planetary K indices as high as 5,
and the mid-latitude index at 6 during the same period.
Coming up on Saturday and Sunday is the HF CW weekend for the Japan
International DX Contest. Unfortunately, as this bulletin is being
written on Thursday night, a major geomagnetic storm is raging. An
interplanetary shock wave passed earth at 1730z on April 6, and
Aurora have been spotted in North America as far south as North
Carolina. The planetary K index for the end of thez day on Thursday
was 8, and the A index was 56. The Boulder K index at 0300z on
Friday is also 8. A severe geomagnetic storm began at 0100z on April 7.
For the next five days, Friday through Tuesday, the expected
planetary A index is 30, 20, 15, 10 and 7. The predicted solar flux
for the same five days is 175, 180, 180, 175 and 170. Solar flux is
expected to rise above 200 again around April 14 and stay there well
into the month of May.
Sunspot numbers for March 30 through April 5 were 225, 248, 287,
301, 252, 184 and 221 with a mean of 245.4. 10.7 cm flux was 205.5,
225.4, 222.9, 219.3, 215.4, 206.7 and 194.4, with a mean of 212.8,
and estimated planetary A indices were 10 meters, 19, 14, 16, 12, 21
and 12, with a mean of 14.9.

EXPLODING STAR FEATURED ON WEB SITE
Wednesday, April 26, 2000 16:04
A spectacular view of an exploding star was released today on a new
web site launched to mark the Hubble Space Telescope's 10th year in
orbit.
The multi-coloured fireball, some 6,500 light years from Earth in the
constellation Aquila, looks like a giant eye in space.
A few thousand years ago a dying star about the same size as the Sun
erupted and threw off its outer layers to create the "planetary
nebula" NGC 6751.
Shells of gas were hurled into space at speeds of 25 miles per
second, glowing with the strong ultra-violet radiation emitted by the
star's hot exposed core.
The celestial cataclysm offers a sobering vision of what is in store
for us.
Our own Sun is predicted to undergo the same death throes in about
six billion years' time. When it happens nothing in the Solar System,
including the Earth, will escape destruction.
The image is one of a number of dramatic pictures now available on
the new Internet site http://hubble.stsci.edu
Others include infant galaxies that existed billions of years ago,
and tall, gaseous pillars that serve as incubators for embryonic
stars.
NGC 6751 shows several poorly understood features. Blue regions mark
the hottest glowing gas, forming a ring around the central stellar
remnant.
Orange and red colours mark the locations of cooler gas, which tends
to lie in long streamers pointing away from the central star, and in
a tattered ring around the edge of the nebula.
The origin of the cooler clouds within the nebula is still uncertain,
but the streamers are evidence that they are affected by radiation
and raging winds from the hot star at the centre. The star's surface
temperature is estimated to be a scorching 140,000C.
Hubble will be decommissioned in 2010 and replaced by the even more
powerful Next Generation Space Telescope.

Propagation Forecast Bulletin 17 - April 28, 2000
Sunspots and solar flux were up this week. The average sunspot
number was up over 40 points and average solar flux rose over 30
points over the past week. Geomagnetic indices have been mostly
quiet, with April 24 the most active day.
Last week's bulletin ARLP016 said that the solar flux should be up
around 220 this weekend, but conditions are not cooperating.
Although activity has been higher this week than last, it is not as
high as expected.
Solar flux is expected to hover around 175 to 185 until April 8,
then dip below 170, and rise to around 200 from May 19 through 28.
The planetary A index prediction indicates unsettled conditions for
Friday. The A index should stay quiet from this weekend until May 6
and 7, when it may rise to 15.
Predicted solar flux for the next five days, Friday through Tuesday
is 180, 175, 175, 180 and 180.
Sunspot numbers for April 20 through 26 were 179, 211, 226, 252,
222, 229 and 197 with a mean of 216.6. 10.7 cm flux was 180.6,
187.3, 201.8, 206.1, 205.6, 202.5 and 189.9, with a mean of 196.3,

Astronomers Spot Most Distant Quasar Ever Observed WASHINGTON (Reuters) -
Astronomers peering across the universe have spotted the most distant
object ever observed, a quasar 26 billion light-years away, researchers
said on Thursday.
This quasar, confirmed as the most faraway object by scientists working
with the Sloan Digital Sky Survey, probably started sending its light in
Earth's direction when the universe was less than a billion years old, the
researchers said in a statement.
The universe is thought to be about 14 billion years old now, give or take
a couple billion years. And it has been expanding since the theoretical
Big Bang that started it all.
Quasars are extremely bright but extremely compact objects thought to be
powered by matter-sucking black holes as massive as a billion suns.
Michael Turner, a spokesman for the Survey at the University of Chicago,
said this means that the quasar is about 26 billion light-years away now,
but because of the expansion of the universe, it used to be a lot closer.
``When it emitted the light, it was only about 4 billion light-years from
the space in the universe where Earth would be eventually,'' Turner said
in a telephone interview. ``It's only when we talk about the most distant
objects that we have to take the expansion of he universe into account.''
A light-year is the distance light travels in a year, about 6 trillion
miles.
Another way to think about cosmic distances and ages is to determine how
bent the light gets as the universe expands. The more bent it gets to the
red end of the spectrum, the older the object is determined to be. This is
known as redshift.
This newly observed object has a redshift of 5.8, the highest ever
measured. It is in fact too red to be seen by the human eye, even with the
most sophisticated equipment. But it was observed through data gathered by
the Sky Survey last month, and scientists confirmed its distance last
week.
An image of the distant quasar can be viewed on the World Wide Web at
http://www.sdss.org.

Propagation Forecast Bulletin 18 - May 5, 2000
It seems odd to view the solar disk at the peak of the solar cycle
and see few sunspots, but that was the case this week. Solar flux, a
measure of 2.8 GHz energy from the sun which correlates roughly with
sunspots and the ionization of the particles which reflect HF radio
waves, were down sharply this week. On Thursday, when this bulletin
was written, the thrice daily solar flux numbers were 133, 134.5 and
134.7. Solar flux has not been this low since January. Average
solar flux for this week dropped over thirty points, and average
sunspot numbers were down over seventy points, when compared to the
previous week.
Geomagnetic conditions were fairly unsettled as well, with planetary
A indices in the double-digits throughout the week, and K indices
often as high as 4. There weren't any severe geomagnetic storms, but
geomagnetic conditions were rarely quiet.
Looking at monthly trends, the average monthly solar flux for
January through April was 159, 174.1, 208.2 and 184.2.
The lower activity should continue for the next few days. Predicted
solar flux for Friday, May 5 through the following Tuesday is 130,
130, 135, 145 and 150. The predicted planetary A index for those
days is 10, 15, 12, 10 and 10.
KA5WQM wrote to remark on poor 10 meter conditions. He said that in
central Oklahoma the band has been unusable since last Thursday.
There are a couple of influences to consider. One is the season.
Ten meters is much better right around the equinox, and we are
moving every day closer to summer conditions when occasional short
skip via sporadic E-layer propagation will be the norm.
Of course the other factor is the lower sunspot activity and solar
flux. Doing a path projection from Oklahoma to Hawaii with a solar
flux of 230, there is a good bet for strong openings on 10 meters
from 1800 to 2230z. Lower the solar flux to 170, and the period in
which strong signals are likely over that path shrinks to 1930 to
2130z. With the solar flux at 130, communication is possible, but
strong openings are much less likely. During this month 15 meters
should be far better for long distance HF communications than 10.
Sunspot numbers for April 27 through May 3 were 163, 238, 142, 126,
121, 108 and 113 with a mean of 144.4. 10.7 cm flux was 183.5,
183.4, 174.9, 169.5, 157.7, 152.8 and 137.3, with a mean of 165.6,
and estimated planetary A indices were 13, 17, 12, 11, 14, 18 and
15, with a mean of 14.3.

Aurora Watching
The Sun is currently entering a peak of storminess, part of
a cycle that lasts 11 years. This causes a stronger "solar
wind," which is a constant stream of charged particles.
When these particles hit the Earth's magnetic field, the
interaction releases visible light, which we in the north
know as the Aurora Borealis, or Northern Lights (there's
the Aurora Australis, or Southern Lights, Down Under).
During these storm peaks, the spectacular auroras can be
visible much further south than usual.

Gravitational Lenses
The hallmark of a scientific theory is that it makes
predictions about the real world that can be tested.
Interestingly, Einstein's theory of general relativity
posed major problems for verification: The differences it
predicted from Newton's laws were so small they were
extremely difficult to measure -- especially with the
technology available in the early part of the twentieth
century.
One prediction that could be checked concerned a
gravitational field's ability to bend light rays, a
phenomenon known as gravitational lensing. Sir Arthur
Eddington used a solar eclipse in 1919 to test the theory.
He looked at the position of a distant star in line with
the edge of the sun during the eclipse (allowing it to be
observed in the daytime). It appeared to be shifted 1.75
arc seconds from its actual place in the sky. The
gravitational field of the sun was bending the light
arriving from that star, providing an early confirmation of
Einstein's theory.

I could not resist posting this image. The solar coronal outburst framed the items you can see listed behind the solar image. Quite extraordinary!
Why were conditions so rough on HF?
Noise can get very high, especially here in the Pacific North West. Signals get weaker than normal on some bands, and deep fades occur. Why?
CME -- that's why. What's a CME? A coronal mass ejection is a huge (like, larger than earth... or bigger!) gas bubble
threaded with magnetic field lines. This bubble is ejected from the Sun. This ejection of gas lasts for several hours, and if
it is directed toward the earth, can result in a very high energy bombardment into our atmosphere and ionosphere. And
our Geomagnetic field becomes very active. A highly active Geomagnetic field degrades radio communications

Yikes, NORTON is hanging your system? I know you mentioned that McAfee caused problems, but I'm surprised about Norton.

OK, here's the info from my Windows 95 guide (the one distributed with new PCs).
1. Restart your computer.
2. When you see the following text: "Starting Windows 95...", press and release the F8 function key. This should display a menu.
3. Type the number for the option you want (or select it with the down arrow key).
I would try the "Safe mode" option, that boots Windows with a minimal configuration, and try uninstalling Norton. Hopefully you'll be able to boot the system normally after that.
Then I'd call Norton to complain. Who needs an anti-virus program that causes more problems than an actual virus??
Good luck!

That's what I did - as I wrote in computer conf/virus topic, I think the problem might just be the factthat I enabled Norton to check all drives at startup. There is one imbedded (know how to rid of them?!) program which is the first to load on the task bar and that is precisely where the problem came and it would shut down completely each time. I slept on it and came up with the same idea as you did and you can see that it worked. I deleted the Norton but kept the zipped download so I can reinstall it if my conclusions are correct - and have it not examine the drives until everything is up and running. However, if it still has a problem with that particular program (which I never use - an internet connection which I do not prefer but NEC did...), it will continue to shut down my computer at every encounter?! Yes?

If it's in your Startup folder, you should be able to delete it from the Startup folder to keep it from running. If it's not there, it might be in the win.ini or system.ini file; at least I think Windows 95/98 still has those files...they would be in the c:\windows or c:\windows\system directory.
The only other place I can think of would be the Windows Registry, but you'd have to hunt through the Registry keys for it. There should be a Registry Editor program (regedit.exe or regedt32.exe) in the c:\windows or c:\windows\system directory.

More Solar Eruptions on June 7, 2000
Space Weather News for June 7, 2000
Following close on the heels of yesterday's two X-class solar flares, a
third powerful X-class flare erupted today at approximately 1545 UT. Soon
afterward, coronagraphs on the orbiting Solar and Heliospheric Observatory
detected a faint full halo coronal mass ejection. It appears to be heading
in the direction of Earth at ~800 km/s. This latest full halo CME will
probably extend the geomagnetic disturbances expected to begin on Thursday
when an interplanetary shock wave spawned by a CME on June 6 collides with
our planet's magnetosphere. Aurora watchers are advised to be on the alert
for Northern Lights beginning after sunset on Thursday, June 8.

A Little Physics and A Lot of String
NASA Science News for June 9, 2000
One day space tethers may be used for boosting orbits, powering
satellites, and even sending payloads to the Moon or Mars -- all
without the expense of conventional propellants. Scientists
discussed this innovative technology at the recent Advanced
Space Propulsion Workshop held in Pasadena, CA.

From that article:
"In one variant of a momentum-exchange tether, the faster-moving tether system grabs a slower-moving satellite in a lower orbit using a grapple at the end of a tether line between 20 and 200 kilometers long.
After orbiting around the Earth once together, the rotating tether system tosses the satellite forward into a higher orbit, somewhat like a roller derby skater grabbing a teammate and slinging them forward. The first skater transfers some of their momentum to the second skater, leaving the first skater going slower afterward. Similarly, the tether system gives some of its momentum to the satellite, ending up in a lower orbit."

A friend made this comment in email this morning:
They used to think about a tether attached to the surface of the earth
with the outer end 100's of miles into space. Theoretically the outer end
would have orbiting velocity. Objects could climb up the tether into
orbit. The problem was the strength and weight of such a tether;
probably impossible.
These present suggested uses for tethers may be more practical.

A solar flare, a CME, and a solar wind disturbance -- all in one day!
Space Weather News for June 10, 2000
The prolific flare-producing sunspot group #9026 unleashed another
moderately strong solar flare today. The eruption was accompanied by a
partial halo coronal mass ejection (CME) that might be Earth-directed. If
so, material from the CME would arrive in the vicinity of our planet on
June 12 or 13. A SOHO coronagraph animation of the event shows a beautiful
billowing CME peppered by speckles and meteor-like streaks resulting from
energetic particles hitting the spacecraft's camera.
Earlier in the day, as predicted, a solar wind disturbance from a CME on
June 7 struck Earth's magnetosphere. Active geomagnetic conditions were
observed for about nine hours, but have since subsided.

**************************
SEVERE GEOMAGNETIC STORM:
Kp Index is at 9. A Index is 118.
We are in a catagory G5 Storm. NOAA's Space Weather
scale indicates the following effects:
Power systems: grid systems can collapse and
transformers experience damage.
Spacecraft operations: extensive surface charging,
problems with orientation, uplink/downlink, and
tracking satellites.
Other systems: pipeline currents reach hundreds of
amps, HF (high frequency) radio propagation
impossible in many areas for one to two days,
satellite navigation degraded for days,
low-frequency radio navigation out for hours, and
the aurora seen as low as the equator.
The Proton Monitor on the Solar and Heliospheric
Observatory is registering solar wind speeds in
excess of 900 km/s
The wave of solar particles - known as a solar
proton event - is already four times more intense
than any other event detected since the launches
of SOHO in 1995 and ACE in 1997. At mid-afternoon
(UT) on July 14th, the storm of particles from
the Sun was still intensifying.

Coronal Mass Ejection
21 July 2000
There is high probability that the CME (Coronal Mass
Ejection) from the major M-class solar flare of
19 July 2000 will arrive today. It is expected to
hit the Earth almost head-on. It is not expected
to be as intense as this last weekend's event.
Auroral activity is expected to increase to storm
levels on 21 July 2000. There is a good chance for
observations of auroral activity from many dark-sky
middle latitude regions, particularly prior to
midnight when the moon is still below the horizon
and optimal observing conditions exist. Moonrise
occurs near local midnight.

Propagation Forecast Bulletin 29 - July 21, 2000
This has been quite a week for solar activity, with blasts of solar
wind dominating space weather news. Saturday was the big day for HF
radio blackouts and aurora, with the planetary A index jumping to an
incredible 152 and the mid-latitude A index at 148. The planetary K
index, updated every three hours, was at 9 for three readings on
Saturday. A K index reading of 9 over a 24-hour period would be
equivalent to an A index of 300. This is big, really big.
These numbers are associated with an extreme geomagnetic storm that
was nearly off the scale. On Friday one of the most powerful solar
flares of the current cycle triggered a storm of protons directed
toward earth. The Solar and Heliospheric Observatory recorded a full
halo coronal mass ejection heading toward earth at greater than
one-million meters per second. Check out animations of this event at
http://sohowww.nascom.nasa.gov/data/CME/.
There are only a few events of this magnitude in the average solar
cycle. The only factor that probably impeded a spectacular aurora
visible far down into the U.S. was that this is the summer season.
A dark evening sky would reveal a rich tapestry of northern lights.
Of course, it being winter in the southern hemisphere, bright
displays were reported in Australia and New Zealand. The author made
a weak attempt Saturday night, walking barefoot into the middle of
the street and trying to peer north past city lights, but no auroral
glow was visible. Seattle is north of the 47th parallel, and
although there were no local reports of aurora, there were
observations as far south as 40 degrees in Europe, Asia, and parts
of Eastern North America. If you point your web browser toward
http://www.sec.noaa.gov/info/kp-aurora.html you will see a nice map
from the June, 1968 issue of Sky and Telescope which shows how far
south aurora may be visible depending on the planetary K index.
What is not clear from this map is whether it shows how far south
the edge of the aurora extends, or how far south it is visible when
looking north.
Another coronal mass ejection emerged on Wednesday, July 19, but the
predicted effect is uncertain because the ejection may not be aimed
squarely at earth. On Thursday the planetary K index went up to 6
for several hours, but by the end of the UTC day it was 3. The
planetary A index for Thursday was 43, and the College A index,
recorded in Alaska, was 57.
The latest forecast shows the planetary A index rising to 50 on
Friday, then dropping to 20 and 15 and then 10 on Saturday through
Monday. Solar flux peaked for the recent short term at 252.9 on
Thursday, and is expected to drop to 245, 235, 230 and 225 on Friday
through Monday. The next short term minimum is predicted around July
28 at 170, followed by another peak above 200 around August 6-9.
The author has received many more inquiries recently asking for
explanations of the various parameters reported in this bulletin.
Although the explanations were repeated six weeks ago, it is
probably time to run them again, and they follow this paragraph.
Feel free to send questions to the author via k7vvvarrl.net.
Amateur Radio operators who use HF generally like increased sunspots
because they correlate with better worldwide radio propagation.
When there are more sunspots, the sun puts out radiation which
charges particles in the earth's ionosphere. Radio waves bounce off
of these charged particles, and the denser these clouds of ions, the
better the HF propagation. When the ionosphere is denser, higher
frequencies will reflect off of the ionosphere rather than passing
through to space. This is why every 11 years or so when this
activity is higher, 10 meters gets exciting. 10 meters is at a high
enough frequency, right near the top of the HF spectrum, that radio
waves propagate very efficiently when the sunspot count is high.
Because of the wavelength, smaller antennas are very efficient on
this band, so mobile stations running low power on 10 meters can
communicate world wide on a daily basis when the sunspot cycle is at
its peak. There are also seasonal variations, and 10 meters tends to
be best near the spring or fall equinox.
The sunspot numbers used in this bulletin are calculated by counting
the sunspots on the visible solar surface and also measuring their
area. Solar flux is measured at an observatory in British Columbia
using an antenna pointed toward the sun tuned to 2.8 GHz, which is
at a wavelength of 10.7 cm. Energy detected seems to correlate with
sunspots and with the density of the ionosphere.
Other solar activity of concern to HF operators are solar flares and
coronal holes, which emit protons. Since the charged ions in the
ionosphere are negative, a blast of protons from the sun can
neutralize the charge and make the ionosphere less reflective.
These waves of protons can be so intense that they may trigger an
event called a geomagnetic storm.
The Planetary A index relates to geomagnetic stability.
Magnetometers around the world are used to generate a number called
the Planetary K index. You can hear the Boulder K index updated
every three hours on WWV, or by calling 303-497-3235.
A one point change in the K index is quite significant. A K index
below 3 generally means good stable conditions, and above 3 can mean
high absorption and poor reflection of radio waves. Each point
change reflects a big change in conditions.
Every 24 hours the K index is summarized in a number called the A
index. A one point change in A value is not very significant. A full
day with the K index at 3 will produce an A index of 15, K of 4
means A of 27, K of 5 means A of 48, and K of 6 means A of 80. You
can find an explanation of these numbers on the web at
http://www.ngdc.noaa.gov/stp/GEOMAG/kp_ap.html.
The number reported here is the Planetary A index, which is a
worldwide average based on the K readings from a number of
magnetometers. The numbers reported on WWV are the Boulder K and A
index, measured in Colorado. Generally the higher the latitude of
the measuring station, the higher the K and A indices reported.
This is because the effects of geomagnetic instability tend to
concentrate toward the polar regions of the globe.
Currently we are near the peak of the solar cycle, so conditions are
generally better because of the increased ionization of the
ionosphere. But along with the increased sunspots come more solar
flares and coronal holes, producing disturbed conditions.
Sunspot numbers for July 13 through 19 were 240, 243, 229, 268, 335,
343 and 342 with a mean of 285.7. 10.7 cm flux was 231.9, 203.9,
213.1, 218.9, 228.3, 261.9 and 249.9, with a mean of 229.7, and
estimated planetary A indices were 33, 35, 152, 46, 9, 13 and 15,
with a mean of 43.3.

Perseid meteor update + an ongoing geomagnetic storm
Space Weather News for August 11, 2000
http://www.spaceweather.com
On the eve of the Perseid meteor shower, sky watchers report seeing 10 to
15 meteors per hour streaming from the constellation Perseus. That's
consistent with an expected peak rate between 30 and 50 visual meteors per
hour before dawn on August 12th. The projected maximum is somewhat weaker
than Perseid maxima of recent years, but observers are also reporting that
this year's Perseid meteors have been pleasantly bright. The shower
should put on a good show for northern hemisphere observers this Saturday
morning.
Readers are invited to send their photos of the 2000 Perseids to
phillips@spacescience.com (Tony Phillips).
There is a chance that Saturday morning sky watchers at higher latitudes
could spot colorful auroras during the Perseid meteor shower. Our planet
is experiencing an ongoing geomagnetic storm triggered by a
southward-pointing interplanetary magnetic field in the vicinity of Earth.
If conditions persist, high latitude (and possibly even mid-latitude)
auroras are possible.

Culprits of Climate Change
NASA Science News for August 29, 2000
For many years, researchers agreed that climate
change was triggered by "greenhouse
gases," with carbon dioxide from burning of
fossil playing the biggest role. However, NASA
funded scientists suggest that climate change in
recent decades has been mainly caused by air
pollution containing non-carbon dioxide
greenhouse gases.

A Close Encounter with a Space Rock
NASA Science News for September 01, 2000
This morning a half-kilometer wide space rock is
zooming past Earth barely 12 times farther from
our planet than the Moon. In cosmic terms, it's a
near miss, but there is absolutely no danger of a
collision. Instead, the encounter offers
astronomers an unusually good opportunity to
study a near-Earth asteroid.

Audacious & Outrageous: Space Elevators
NASA Science News for September 07, 2000
Science-fiction writer Arthur C. Clarke was once
asked when the "space elevator," a
notion he helped to popularize, would become a
reality. Clarke answered, "Probably about 50
years after everybody quits laughing."
Nowadays NASA scientists are taking the idea
seriously. In fact, they've compiled plans that
could turn the space elevators of science fiction
into a real-life mass transportation system to
space by the end of the 21st century.

Where did all the sunspots go?
Space Weather News for Sept 12, 2000
http://www.spaceweather.com
Telescopes monitoring the Sun recorded something extraordinary yesterday
-- the solar disk was nearly devoid of spots. With solar maximum in full
swing, the Boulder sunspot number dropped to its lowest value of the year.
In spite of the "blank Sun," our planet could be in for a bit of space
weather on Tuesday if, as expected, a solar coronal mass ejection that
left the Sun on Saturday strikes a glancing blow to Earth's magnetosphere.
The impact could trigger modest geomagnetic activity.
In other space weather news, astronomers have discovered a bright Near
Earth Asteroid that will pass by our planet on Sept. 17. Amateur
astronomers can monitor the fast-moving space rock in 8-inch or larger
telescopes.

which includes photo settings that worked well during the geomagnetic

Also, the bright Near-Earth asteroid 2000 RD53 will fly by our planet on
September 17, barely 11 times farther away than the Moon. Amateur
astronomers with 8 inch or larger telescopes can spot the space rock as it
zooms by. (Note: There is no relationship between the asteroid and the
CMEs.)

Geomagnetic activity alert + near-Earth asteroid news
Space Weather News for Dec. 19, 2000
http://www.spaceweather.com
METEORS & AURORA: Sky watchers who venture outside to view the Ursid
meteor shower Thursday night or Friday morning might also spot aurora
borealis. A coronal mass ejection that left the Sun on Monday is likely
to buffet Earth's magnetosphere later this week. Forecasters estimate a
20% chance of severe geomagnetic activity when the CME arrives.
NEAR-EARTH ASTEROIDS: A newly-discovered near-Earth asteroid, 2000 YA,
will pass just two lunar distances from Earth on Dec. 22nd. There's no

There was a very interesting piece this morning on NPR on the Saturn moon,
Euuropa. It seems there may be water beneath the ice that may support
life. Even though the sun's energy is very distant, there is some kind of
gravitational tide effect from Saturn and other moons that may be enough
to generate higher temperatures and enable liquids under the icy surface.
There is some kind of underwater sub expedition planned by NASA in the
next 10 years. This could be an exciting development, I haven't searched
o the net yet, but I'm sure there's more out there on this, on NPR.org's
site for sure.

Correction, substitute Jupiter for Saturn. Big detail.
EUROPA & HOW LIFE BEGINS $
NPR's Richard Harris explores what it would take for life to begin elsewhere in the solar system. Pictures released yesterday of Jupiter's moon Europa suggest that the chemicals necessary for life may exist in large frozen oceans there -- just waiting for the right conditions to sprout life. On Earth, oceanographers think that life may have begun in a similar primordial soup at the bottom of the ocean. They're looking at unique heat-resistant organisms that live next to hot-gas vents on the ocean floor.

A meteor outburst, after all....
Space Weather News for Dec. 22, 2000
http://www.spaceweather.com
METEORS: Sky watchers in Europe and on the US west coast spotted a modest
outburst of Ursid meteors Thursday night. Astronomers had hoped for a
more impressive display, but the flurry of faint shooting stars was
nevertheless welcomed because it confirmed a new model of cometary debris
streams.
AURORA WATCH: Conditions may be favorable for high-latitude auroras
tonight. The interplanetary magnetic field (IMF) near Earth turned
sharply southward after a solar wind disturbance arrived in the
neighborhood of our planet. South-pointing IMFs make our magnetosphere
more vulnerable than usual to solar wind gusts -- additional gusts could
trigger Northern Lights.

Russian PM Orders Demise of Aged Mir Space Station - Jan 5 2001 7:01AM
MOSCOW (Reuters) - Russian Prime Minister Mikhail Kasyanov has
signed a resolution ordering that the aged Mir space station be taken
out of orbit and sunk into the ocean early this year, the Russian space
agency said Friday.
A spokesman for space agency Rosaviakosmos said that Kasyanov
had signed the document on Dec. 30, formalizing a government
decision from November to take the nearly 15-year-old Mir, originally
intended to orbit Earth for just five years, out of service due to a lack
of funding.
The order calls for establishing a commission to determine how Mir will
be brought down, and also says that resources that had been
dedicated to the orbiter were to be focused on the $60 billion
International Space Station (ISS). The ISS, a 16-nation venture, uses
technology developed for Mir, which for years was the world's only
manned space station.
During its lifetime Mir helped Soviet and Russian cosmonauts set a
string of space endurance records that have been the nation's pride --
and the envy of the envy of the better-funded United States.
But in recent years a spate of mishaps dulled the revolutionary space
station's image, including a near-catastrophic collision with a cargo craft
and a communications failure on Christmas day last month that
sparked fears that Mir was spinning out of control.
U.S. space officials have pushed Russia to dump Mir, saying it drained
sparse resources that would be better spent on Russia's role in the
International Space Station.

Russia to Lauch Mir Space Station's Nemesis
BAIKONUR, Kazakhstan (Reuters) - Russia launches a cargo rocket on
Thursday to help it bury the last vestige of the Soviet Union's
ambitious space exploration program -- the record-breaking Mir space
station.
The unmanned Progress M1-5 vessel, one of the craft that were used
to ferry food and water to Mir, will this time only carry enough fuel for
its own engines to guide Mir out of orbit and into the Pacific Ocean.
The rocket is due to blast off from Kazakhstan's windswept Baikonur
cosmodrome at 0656 GMT. It is scheduled to dock four days later with
the 130-tonunmanned space station.
In early March, both will crash into the ocean.
Space officials have said up to 40 tonnes of debris will reach the
earth's surface at a speed high enough to smash through two meters
(6.5 feet) of reinforced concrete.
Russia has said it expects Mir to hit earth on March 5-6 but the precise
date and time will depend on solar activity and the success of the
Progress mission.
If the automatic docking controlled from the earth fails, a Russian crew
of Gennady Padalka and Nikolai Budarin is ready to take off in 12 days
to guide the station out of orbit manually.
This would end the 15-year history of Mir, whose first part was launched
into orbit on February 20, 1986, with an originally designed life-span of
just three years.
Russia, struggling to overcome an economic crisis after almost a
decade of steep recession, could not find $200 million needed to
maintain the station. It decided in November to dump Mir into the
ocean on its 15th birthday.
Yuri Koptev, head of Russia's space and aviation agency, said last
month there was little point in maintaining a station where cosmonauts
spent 80 percent of their time on repairs.
Cash-strapped Russia, where power cuts regularly plunge whole regions
into darkness and many people use kerosene lamps and home-made
stoves to survive the winter, has long regarded the station as an
example of its technological genius.
MANY RECORDS SET
The station, visited by 28 long-term expeditions with a total of 106
cosmonauts, has set many records.
Kazakh cosmonaut Talbat Musabayev spent more than 30 hours in one
month working outside the station to secure his place in the Guinness
Book of Records.
Russian Sergei Avdeyev, who spent 747 days in space, remains the
only cosmonaut in the world to have toasted the New Year three times
in orbit.
But Mir has also seen a number of frustrating glitches.
In February 1997, fire broke out when cosmonauts tried to change an
air filter. A few months later, Mir's energy supply fell dramatically after
a Progress cargo craft hit it during docking and damaged its solar
batteries.
In September 1997, a computer failed, leaving Mir spinning aimlessly.
Two years later, the station went into hibernation after Mission Control
shut down its main computer by accident.
After the dumping of Mir, Russia will focus on the ambitious $60 billion,
16-nation venture to build the International Space Station (ISS).
But for many who remember the heyday of the Soviet space industry,
when state funds were spent generously on the sector to dazzle the
West with its achievements, the dumping of Mir will mean the end of
an epoch.
"Thursday's launch would have been nothing out of the ordinary if it
wasn't aimed at guiding Mir out of its orbit," Nikolai Zelenshchikov, first
deputy head of the Energiya corporation that runs Mir, told Reuters.
"This is sad, but we understand that Mir's work must come to an end
and we should then switch over to building the ISS."

I was reading yesterday that a New York museum has de-classified Pluto, stripping it of planetary status.
Apparently Pluto is twice as big as the next biggest asteroid in the Kuiper Belt (not sure of my terms here, memory plays trick), but only about an eighth as big as Uranus.
So the museum's exhibit shows only 8 planets, and they reckon Pluto will be "happier as the king of the Kuiper Belt rather than the smallest, furthest planet". Who even knew that asteroids orbited the sun beyond the planets? Not me.

NEAR Spacecraft Leaves Orbit to Land on Asteroid
LAUREL, Md. (Reuters) - Space probe NEAR Shoemaker left its yearlong
orbit of monster asteroid Eros and headed toward the big rock's surface
on Monday, the first time any craft tried to land on this kind of cosmic
object.
"We're on a flight path now that will take us to the surface," mission
Director Bob Farquhar said in an update from the project's
headquarters outside Washington.
The bus-sized spacecraft was never meant to land -- it orbited the
21-mile-long asteroid for a year, taking some 160,000 images and
beaming them back to Earth -- but it was at the end of its expected life
and had satisfied all its objectives, so Farquhar and others decided a
landing attempt could provide some "bonus science."
To get the solar-powered ship out of its 21-mile-high orbit, thrusters
were fired around 10:31 a.m. EST to send it toward the asteroid. Four
more burns were scheduled to slow NEAR to what scientists hoped would
be a soft landing.
The landing was scheduled for about 3 p.m. EST, but because it will
take 17.5 minutes for light to travel the 196 million miles from the
craft to Earth, scientists at Johns Hopkins University's Applied Physics
Laboratory in Laurel said they would not have much information at the
exact instant of touchdown.
NEAR Shoemaker -- short for Near Earth Asteroid Rendezvous and in
honor of the late astronomer Gene Shoemaker -- was supposed to
come down to Eros at a leisurely speed of from 2 to 7 mph. However, if
things went awry during the complicated maneuver, the landing could
be much faster and much harder. The craft could be flattened on
impact.
If all went as planned, however, NEAR would take images as it edged
closer to Eros and send them back to Earth, as it has since it first
started orbiting the asteroid on Valentine's Day 2000.
When it landed, NEAR could hit one of the huge boulders that dot the
asteroid's surface, or become buried in one of the so-called sand
ponds. Or it could go into "ostrich mode" and turn its antenna toward
the surface and away from Earth, and never be heard from again.
It took NEAR about four years to travel a 2 billion-mile, looping route
to Eros, named for the Greek god of love. At a cost of $223 million, the
mission is considered a model for the cheaper, faster space flights
envisioned by NASA.
The National Aeronautics and Space Administration has already rated
the mission a success for the data it has collected about Eros, a
so-called near-Earth asteroid that has the potential to collide with the
planet in 1.5 million years or so.
If Eros ever did hit Earth, the results would be catastrophic; indeed, a
much smaller space rock is thought to have been responsible for
wiping out the dinosaurs 65 million years ago.
Astronomers were also interested in the composition of this rock
because it is probably a remnant from the formation of the rocky inner
planets of our solar system some 4.5 billion years ago.

NEAR Spacecraft Lands on Asteroid
COLUMBIA, Md. (AP) - The NEAR spacecraft touched down on the
barren, rocky surface of Eros, successfully completing history's first
landing on an asteroid.
NEAR's landing at about 3:05 p.m. EST Monday was confirmed when
Mission Control received a beacon signal from the craft resting on the
surface of Eros, some 196 million miles from Earth.
``I am happy to report that the NEAR has touched down,'' said Robert
Farquhar, mission director. ``We are still getting signals. It is still
transmitting from the surface.''
Engineers watching from monitors from Mission Control broke into
applause at confirmation of history's first landing of a manmade object
on an asteroid. The mission, controlled by the Johns Hopkins
University Applied Physics Laboratory, also was the first into deep
space operated by a non-NASA center.
NEAR flawless performed five rocket firings, starting Monday morning,
to drop it out of a 15-mile orbit of Eros and slow it toward the surface.
Early indications are that Mission control completed its plan to guide
NEAR to a feather-like touchdown by slowing its velocity, relative to the
surface of the asteroid, to about the speed of a fast walk, 3 to 5 miles
an hour.
The landing completes a five-year, 2-billion-mile mission for the robot
craft and boosts the technical experience in putting spacecraft on
objects with extremely light gravity.
``This gives us a lot of practice,'' said Ed Weiler, NASA's chief scientist.
``We'll eventually want to land on comets because they hold the clues
to beginnings.''
Weiler said the experience gained in the NEAR landing attempt on Eros
can be applied in about a decade when NASA may launch a landing
mission to a comet.
NEAR became the first spacecraft to orbit an asteroid when it arrived at
Eros, an object named for the Greek god of love, on Valentine's Day
last year. The mission had been scheduled to end on Wednesday,
anniversary of achieving orbit.
Farquhar said it was decided to attempt the landing to squeeze a final
bit of science out of the $223 million mission.
No matter how the landing attempt ended, Weiler said, earlier, NEAR
was ``a total success. It returned 10 times more data than expected.''
Officials targeted NEAR to land on Eros at the edge of a deep
depression called Himeros. Scientists picked this spot because it is
thought to be on the edge of two different geologic formations.
During the final hours of its descent, NEAR furiously took pictures of
Eros' surface as it drew closer and closer. Scientists hoped the final
shots before impact would clearly show rocks as small as a fist, an
unprecedented close-up view of an asteroid.
``In those final images, we'll be seeing objects that are just a few
inches in resolution,'' said Andrew Cheng, chief project scientist of
NEAR.
Farquhar had warned in advance that landing NEAR n Eros is
exquisitely ``tricky.''
NEAR was not designed to land anywhere. Shaped like tin can attached
to four solar panels, the craft was not equipped with wheels or braces
to absorb the landing force.
Weiler commented, ``This is not a landing. It is a controlled crash.''
Eros has very light gravity, about one-thousandth that of Earth, which
means that an object, such as NEAR, weighing 1,100 pounds on Earth,
would weigh only slightly over a pound in the gravity field of Eros. A
quarter, dropped from head-high on Eros, would take five seconds to
fall to the surface.
Weiler said the final descent of NEAR was actually slower than the
asteroid's rotation and there was risk that the spinning space rock
could actually swat the craft back into orbit.
NEAR traveled more than 2 billion miles during its five-year mission. It
was launched Feb. 17, 1996, into an independent solar orbit. NEAR
swung by the Earth once to pick up speed and then streaked outward
toward Eros, an asteroid in an elongated orbit that nears Mars and
approaches Earth's orbit.
In December 1998, a rocket firing designed to put the craft into orbit of
Eros failed and NEAR sped past the asteroid. A second rocket firing
series was successful and the spacecraft eventually returned to Eros
and slipped into history's first orbit of an asteroid.
The craft spent the last year snapping photos of Eros, second- largest
of the asteroids that approach the Earth's orbit. The NEAR instruments
also gathered information about the asteroid's composition, structure,
size and shape.
NEAR was built and operated under a faster-better-cheaper space
exploration philosophy developed at NASA. Under the direction and
control of the Johns Hopkins University Applied Physics Laboratory, the
spacecraft was designed, built and launched in just 26 months. Some
deep space explorations have taken a decade or more to mount. NEAR
is also the first deep-space mission to be operated by a non-NASA
space center.

NEAR AND EROS MEET
Although given no better than a 1-in-100 chance of survival, the Near
Earth Asteroid Rendezvous (NEAR) spacecraft thumped onto the dusty,
boulder-strewn surface of minor planet 433 Eros on Monday and lived to
tell about it. The spacecraft continued to broadcast to Earth after
touching down at an estimated 1.5 meters per second at 3:05 p.m. EST
(20:05 Universal Time). As mission personnel looked on anxiously, NASA
tracking stations in California and Spain continued to receive a
low-power signal (but no data) after the first-ever landing on a small
solar-system body.
The landing sequence began about 4 hours earlier, as a rocket firing
forced NEAR-Shoemaker out of its 35-kilometer-high orbit and sent it
on a collision course with Eros. Four more rocket firings, beginning
at altitude of 5 km, slowed the craft during its 47-minute freefall.
Engineering data and altitude measurements showed that the spacecraft
descended to the surface just as planned, perhaps bouncing once before
settling down tipped to one side and resting on the corners of two
solar-cell panels. The touchdown site is on the shoulder of Himeros, a
broad depression in the southern hemisphere.
NEAR Shoemaker's onboard camera radioed more than 50 pictures as the
surface drew closer. The landscape looked smooth and dust-covered for
the most part, peppered with myriad boulders ranging from house- to
fist-size. But mission scientists were most surprised by the lack of
small impacts. "We are absolutely amazed by the absence of small,
fresh craters," exclaimed imaging-team leader Joseph Veverka, as well
as by numerous shallow sinkhole-like depressions. The final frame,
taken from a height of 125 m, showed an area 6 m wide and revealed
details only about 1 centimeter across. NASA had intended to cease
tracking the spacecraft on February 14th, when the mission was to
officially end. However, since the spacecraft survived, it has been
granted a reprieve as scientists try to glean more useful data from
the probe.
LIFE UNDER FROZEN MARTIAN LAKES?
The Antarctic lake Vostok, has received much attention for being an
analog to the Europan surface. Scientist believe that the lake,
covered by nearly 4 kilometers of ice, closely resembled the proposed
ocean on Jupiter's frozen moon. Both bodies of water seemed to have
formed by geothermal heating, and because the ice above is so thick,
both seas remained sealed from sunlight and air for millions of years.
Thus, if life exists in Lake Vostok (drilling missions have yet to
reach the liquid layer), it's plausible that life could also exist on
Europa.
However, scientists now believe that Vostok better resembles another
planet suspected of once harboring life: Mars. Natalia Duxbury (Jet
Propulsion Laboratory) and her colleagues suggest that Vostok did not
form by geothermal heating after all. Instead models of Vostok created
by the researchers imply that the Antarctic lake was originally an
open body of water that froze over between 5 and 30 million years ago.
And as such, any life found inside the lake would be older than the
Antarctic ice sheet.
This model bares a striking resemblance to the red planet. The Martian
north pole is known to be covered with ice. However, Mars's axial tilt
has changed dramatically throughout the planet's lifetime and the
current polar regions were once much warmer. Therefore it is easy to
assume that sometime in Martian history, the poles, like Duxbury's
model of Vostok, were once open bodies of water that later froze over.
Assuming life was present while Vostok was an exposed lake, and
assuming life is seen the lake today, it seems possible that if life
existed in an ancient Martian polar lake, it may still be there too.
The European Space Agency's Mars Express orbiter, scheduled for launch
in 2003, will examine the Martian poles for buried liquid water. A
similar experiment will eventually be flown to Europa as well. Details
of the study can be found in the January 25th Journal of Geophysical
Research.
PLUTO'S PALETTE REVEALED
During the 1980s Pluto and its satellite Charon repeatedly passed in
front of and behind one another as seen from Earth, a fortuitous
series of "mutual events" whose light curves allowed astronomers to
create crude maps of Pluto's surface. The maps showed that the half of
Pluto facing Charon was distinctly pink with a broad, dark belt
girding its midsection. Theorists surmised that the planet's
equatorial zone contained reddish organic byproducts derived from the
frosts of nitrogen, methane, and carbon monoxide that cover the
adjacent brighter regions.
However, when Eliot F. Young (Southwest Research Institute), Richard
F. Binzel (MIT), and Colorado high-school student Keenan Crane
analyzed four mutual events recorded in both blue and yellow light,
they got an unexpected surprise: the dark band actually consists of
separate blue and yellowish red regions. As the trio of researchers
report in the January issue of Astronomical Journal, these
variegations may indicate that bluish frosts are mixed with dark
material in varying amounts or that the equatorial belt has received
different amounts of heat and radiation to drive the organic reactions
in the icy surface.
COMET MCNAUGHT-HARTLEY HIGH IN HERCULES
Comet McNaught-Hartley (C/1999 T1) is still moving north, reaching yet

THIS WEEK'S "SKY AT A GLANCE"
Some daily events in the changing sky, by the editors of Sky & Telescope.
FEB. 18 -- SUNDAY
* Some doorstep astronomy: This is the time of year when the bright
constellation Orion stands at its highest in the south in early evening.
Look for Orion's Belt, a diagonal row of three stars, in its middle.
FEB. 19 -- MONDAY
* Jupiter's Great Red Spot should cross Jupiter's central meridian (the
imaginary line down the center of the planet's disk from pole to pole)
around 11:01 p.m. EST. The "red" spot is currently very pale orange-tan. It
should be visible for at least 50 minutes before and after in a good 4- or
6-inch telescope if the atmospheric seeing is sharp and steady. For a list
of all predicted Red Spot transit times, see
http://www.skypub.com/sights/moonplanets/redspot.html .
* Jupiter's largest moon, Ganymede, casts its shadow on the planet from
9:42 to 11:55 p.m. EST.
FEB. 20 -- TUESDAY
* Mars is near Beta Scorpii this morning and Wednesday morning. Take a
look with binoculars! In a telescope, Beta is revealed as a fine double star.
FEB. 21 -- WEDNESDAY
* More doorstep astronomy: Once you've found Orion and his Belt high in
the south (see Sunday above), follow the line of the Belt to the lower left
for about two fist-widths at arm's length to find brilliant Sirius. In the
opposite direction, Orion's Belt points roughly to the group of bright
Jupiter, yellow Saturn, and orange Aldebaran.
FEB. 22 -- THURSDAY
* Jupiter's Red Spot transits around 8:32 p.m. EST.
FEB. 23 -- FRIDAY
* New Moon (exact at 3:21 a.m. EST this morning).
FEB. 24 -- SATURDAY
* Shortly after sunset, look just above the western horizon, far below
Venus, for the hairline crescent Moon.

SOLAR ACTIVITY: This week the face of the Sun looked remarkably blank as

collapsed on the Sun and the eruption sent a coronal mass ejection toward
Earth. The expanding cloud will likely reach our planet on Saturday,
March 3rd, and trigger high latitude auroras.

Propagation from ARRL
Solar flux declined this week, having reached a short-term peak a
week prior to Wednesday. But average daily solar flux and sunspot
numbers were higher this week than last. Daily sunspot numbers
reached a peak of 174 on Monday. This is the highest it has been
since February 9, when it was 179, or January 23, when it was 178.
Geomagnetic conditions have been quiet, with A indices in the
single-digits. Quiet conditions should continue, although there is a
possibility that sunspot group 9373, currently at the center of the
solar disk oriented toward earth, could produce some solar flares on
Thursday or Friday. You'll hear the results on the WWV reports a few
days later if the K index rises above 3.
Solar flux is expected to be around 135 on Friday and 130 for the
following few days, then rise to around 145 on March 22-24. By
comparison, a year ago the average sunspot number and solar flux
reported in this bulletin (ARLP011) was respectively 193.4 and
194.9.
Scott Craig has a revised version of his Solar Data Plotting
Utility, which works with the data presented in this bulletin. The
new version was released last week, and has a new feature which can
connect to the internet and automatically download the solar data
from an ARRL FTP site. His website is at
http://www.craigcentral.com, and the software is at
http://www.craigcentral.com/sol.htm.
Next week is the spring equinox, with anticipated spring propagation
conditions. 15 and 20 meters should be open later into the evening,
with 20 meters possibly open all night. 10 meters should improve
around the change of seasons, but will probably degrade for
worldwide propagation as spring moves toward summer.
Sunspot numbers for March 8 through 14 were 98, 113, 131, 139, 174,
110 and 159 with a mean of 132. 10.7 cm flux was 167.2, 161.4,
160.1, 157.8, 157.6, 147.3 and 142.2, with a mean of 156.2, and
estimated planetary A indices were 6, 6, 5, 4, 10, 7 and 7 with a

Astronomers have seen dark matter directly for the first
time. Ben Oppenheimer of the University of California at
Berkeley and colleagues in the US and UK have discovered
a new kind of white dwarf that could account for up to a
third of the 'dark' matter in the Universe. The extremely
dim burnt-out stars were found in the 'galactic halo'
that surrounds the Milky Way. Oppenheimer's team believes
they represent part of the invisible matter - proposed to
exist 70 years ago - that binds together galaxies and

Solar activity is on the rise...
Space Weather News for March 27, 2001
http://www.spaceweather.com
SOLAR ACTIVITY: In recent days the Boulder sunspot number has rocketed to
339, its highest level since July 2000. At least one large sunspot group
has a complex magnetic field that could harbor energy for powerful solar
flares. Forecasters estimate a 20% chance of an X-class eruption during
the next 24 hours.
AURORA WATCH: An interplanetary shock wave buffeted Earth's magnetosphere
Tuesday morning and another may be following close behind. A coronal mass
ejection that left the Sun on March 25th will arrive late Tuesday or
Wednesday and possibly trigger additional geomagnetic disturbances. In
recent days Alaskan sky watchers have enjoyed some of the best auroras of
the current solar cycle. Check out our gallery of aurora photos for the
latest images.

Massive Sunspot May Lead to Geomagnetic Storms
The Sun has developed the largest sunspot seen in 10 years according to
images from SOHO, a satellite that monitors the Sun. The size of this
enormous spot is equivalent to the total surface area of 13 Earths. The
sunspot region has already produced a coronal mass ejection and a powerful
solar flare, and these are likely to lead to geomagnetic storms.
The worldwide network of Magnetic Observatories operated by the U.S.
Geological Survey (USGS) is monitoring the geomagnetic field that is
expected to become quite disturbed as result of this solar activity. While
geomagnetic storms give rise to the beautiful Northern lights, they can
also pose a serious threat for commercial and military satellite operators,
power companies, astronauts, and they can even shorten the life of oil
pipelines in Alaska by increasing pipeline corrosion.
Geomagnetic storms occur when plasma, a hot ionized gas of charged
particles produced by eruptions on the Sun, impacts the Earth's magnetic
field causing it to fluctuate wildly. These fluctuations cause currents to
flow in conductors on the ground and in space. Solar eruptions can produce
billions of tons of plasma traveling at speeds in excess of a million miles
an hour. The first eruption should hit the Earth's magnetic field some time
on Friday, March 30, and the second on Saturday. The geomagnetic field will
likely become very active and there is a strong chance of Aurora sightings
The USGS provides valuable geomagnetic data to a wide variety of users and
organizations that are affected by geomagnetic storms. The agency operates
a network of 14 magnetic observatories that continuously monitor the
Earth's magnetic field. The data are collected in near-real time via
satellite to a downlink center located in Golden, Colo., and provided to
numerous customers including NOAA's Space Environment Center and the U.S.
Air Force Space Command Center. Plots of the data from these observatories
can be seen on-line at: http://geomag.usgs.gov/frames/plots.htm
The SOHO satellite is operated jointly by the European Space Agency and
NASA.
As the nation's largest water, earth and biological science, and civilian
mapping agency, the USGS works in cooperation with more than 2000
organizations across the country to provide reliable, impartial, scientific
information to resource managers, planners, and other customers. This
information is gathered in every state by USGS scientists to minimize the
loss of life and property from natural disasters, to contribute to the
conservation and the sound economic and physical development of the
nation's natural resources, and to enhance the quality of life by
monitoring water, biological, energy, and mineral resources.

The Crumbling Comet LINEAR A
Space Weather News for May 2, 2001
http://www.spaceweather.com
Yesterday astronomers reported that the nucleus of comet C/2001 A2
(LINEAR) has apparently split in two. This icy visitor from the outer
solar system is growing in brightness as it approaches the Sun and could
soon become a faint naked-eye object. Sky watchers with modest telescopes
or binoculars can spot the fuzzy fragmenting comet near the feet of Orion
after sunset. The comet is rapidly gliding toward southern skies, so
southern hemisphere observers will enjoy the best views in the days and
weeks ahead.

GeoStorm Warning, plus a crumbling comet and a durable sunspot
Space Weather News for May 12, 2001
http://www.spaceweather.com
GEOMAGNETIC STORM WARNING: Our planet entered a high speed solar wind
stream on Saturday, May 12th, which triggered a moderate geomagnetic
storm. Sky watchers, especially those at high latitudes, should be alert
for glowing auroras tonight near local midnight.
THE SUNSPOT THE WOULDN'T DIE: Holographic images of the far side of the
Sun reveal an old friend: active region 9393, the largest sunspot of the
current solar cycle and the source of the most powerful x-ray solar flare
ever recorded. The giant spot, which is probably now just a shadow of its
former self, has already transited the Earth-facing side of the Sun twice.
If AR9393 persists for another week it will emerge into direct view for a
rare third transit.
BRIGHTENING COMET: Southern hemisphere observers report that comet C/2001
A2 (LINEAR), which split into two pieces last month, has surged in
brightness again.

NASA's Ames Research Centre Sponsors New Interactive Research Project
NASA's Ames Research Centre is sponsoring a new interactive research project to help identify, map, and classify impact craters on the surface of the planet Mars; the project is modelled on the popular SETI@Home project which employs personal computers to scan for possible intelligent radio signals from extraterrestrial civilisations. In the Ames project, participants are taught how to identify and mark impact craters in photographs obtained from the Viking 1 & 2 Orbiters, as well as from the Mars Global Surveyor Spacecraft currently in orbit around the Red Planet. Using their computer's mouse, the "ClickWorkers" as they're called, select four points around the crater's rim, which the computer uses to draw a circle based on the points selected. With this, the computer logs the size of the crater as well as it's longitude and latitude.
The purpose behind this exercise is to catalogue the huge volumes of data that have be gathered over the years by the various probes to Mars, but NASA is suffering from an embarassment of riches that would easily swamp individual researchers; so by employing the computer power spread around the world amongst private citizens, NASA can use many people to tackle the problem in parallel. The project's current status is experimental, but if it's successful, it's scope maybe expanded to include other martian surface features, and may even go on to include other solar system bodies, including Io and Europa.
The project can be found at http://clickworkers.arc.nasa.gov but there are two proviso's in accessing it; first, it requires Netscape 6 to run, and secondly, the site is extremely popular amongst people who want to make a real contribution to planetary science, so it can be very difficult to access at times. But if you're interested in helping build up our knowledge on Mars, and maybe familiarizing yourself a little more with it, check it out!

Binary asteroid to fly by Earth this weekend
Space Weather News for May 24, 2001
http://www.spaceweather.com
Late Friday, May 25th, the near-Earth asteroid 1999 KW4 will fly by Earth
13 times farther from our planet than the Moon. The space rock will be
brighter than 11th magnitude for much of the time between now and May
28th, making it an easy target for amateur astronomers with mid-sized
telescopes and CCD cameras. Yesterday, radar astronomers using NASA's
Goldstone Planetary Radar to monitor the approaching asteroid announced
that 1999 KW4 is a binary system. Visit spaceweather.com for more
information and (possibly) images of the asteroid as it passes our planet.

The Arietid Meteor Shower Peaks This Week
Space Weather News for June 5, 2001

The annual Arietid meteor shower peaks this week on Thursday, June 7th.
The Arietids are unusual because they are daytime meteors -- most of them
streak through the sky unnoticed while the bright Sun is overhead.
Nevertheless, early risers on Thursday could spot some beautiful
"Earthgrazing" Arietids during the dark hours before dawn. Later in the
day, after the Sun rises, you can listen to the shower by tuning in to
NASA's online meteor radar.

Looming like a giant flying saucer in our outer solar system, Saturn puts on a show as the planet and its magnificent ring system nod majestically over the course of its 29-year journey around the Sun. These Hubble images, captured from 1996 to 2000, show Saturn's rings open up from just past edge-on to nearly fully open as it moves from autumn towards winter in its Northern Hemisphere.

Scientists Claim to Revive Alien Bacteria
By Rossella Lorenzi, Discovery News
May 10 � Italian researchers claim to have found conclusive evidence
that life on Earth arrived from outer space.
Bruno D'Argenio, a geologist working for the Italian National Research
Council, and Giuseppe Geraci, professor of molecular biology at Naples
University, identified and brought back to life extraterrestrial
microorganisms lodged inside 4.5 billion-year-old meteorites kept at
Naples' mineralogical museum.
"When in contact with a physiological solution, they became visible
and began to move," D'Argenio said while presenting the finding at the
Italian Space Agency yesterday.
The bacteria, called "cryms" (for crystal microbes) by the
researchers, remained dormant for billions of years and survived
extreme ambient conditions � a clear indication, according to the
researchers, that "life can exist everywhere in the solar system,
though in a quiescent state."
Once brought back to life, the cryms were cloned by the researchers
and their DNA analyzed.

The Biggest Explosions in the Solar System
NASA Science News for June 12, 2001
Solar flares have vexed astronomers since they were discovered nearly a
century and a half ago. The powerful explosions do things we simply don't
understand. NASA's upcoming HESSI mission might finally solve the riddle
of flares by making x-ray and gamma-ray pictures of the eruptions. What
we learn could have down-to-Earth benefits and shed light on mysterious
happenings far outside the solar system.

The latest news from Astronomy Now and Spaceflight Now
TEMPERATURE MAP OF IO PRESENTS A PUZZLE
---------------------------------------
Earth's tropics are hotter than the polar regions for a good reason, so scientists are puzzled that the same pattern doesn't show on Jupiter's moon Io. Powerful volcanoes and the previous day's sunshine warm the nighttime surface of Jupiter's moon Io, as seen in this image from NASA's Galileo spacecraft.
http://spaceflightnow.com/news/n0106/24iomap/
EUROPA'S FROZEN SURFACE
-----------------------
Europa, a moon of Jupiter, appears as a thick crescent in this enhanced-color image from NASA's Galileo spacecraft. Reddish linear features are some of the cracks and ridges, thousands of kilometers long, which are caused by the tides raised by the gravitational pull of Jupiter. Also visible are a few circular features, which are small impact craters.

A Meteor Shower This Week?
Space Weather News for June 25, 2001
http://www.spaceweather.com
METEOR SHOWER: On June 26th and 27th Earth will pass through the dusty
debris trail of comet 7P/Pons-Winnecke, triggering the annual "June
Bootid" meteor shower. Most years the June Bootids are meek: a typical
shower consists of only a few visible meteors each hour -- but not always.
In 1998 sky watchers enjoyed an intense Bootid outburst. What will happen
this year? No one knows, but meteor enthusiasts will be watching the
heavens for a possible flurry of shooting stars. Tune in to
SpaceWeather.com for observing tips and more information about the shower.
And don't forget to try listening to the June Bootids using our online
meteor radar.
SOLAR ECLIPSE: SpaceWeather.com's growing gallery of images from last
week's solar eclipse now includes sounds as well. Listen to audio clips
that reveal the excited reactions of onlookers before and during totality.

Mars is very orane compared with other things in the nigth sky. I am hoping tonight will be my turn to see it. Yup, Comet Linear. Go take a look at the Sky and Telescope page I posted yesterday - or see below!
COMET LINEAR HEADING INTO NORTHERN SKIES
Northern Hemisphere observers should finally get a peek at Comet
LINEAR (C/2001 A2) later this week as it quickly moves through Cetus.
The comet was closest to the Sun on May 24th, but will be closest to
the Earth on June 30th (37 million kilometers). Observers at
midnorthern latitudes will see the comet climb higher above the
east-southeast horizon each morning. By the end of the week, Comet
LINEAR should be 10 to 25 deg. high (depending on your latitude) by
the first hints of dawn. LINEAR has faded a little since reaching 3rd
magnitude last week, but it remains a naked-eye object. In a week's
time, however, the comet could fade even more or have yet another
outburst. The comet remains high in the morning sky for Southern
Hemisphere observers, where it will be more than halfway to the zenith
in the eastern sky before dawn. Here are coordinates for Comet LINEAR
for 0 hours Universal Time (in 2000.0 coordinates) for the coming
week:
R.A. Dec.
Jun 23 2h 12m -17.8 deg.
25 1 50 -15.0
27 1 27 -11.9
29 1 04 - 8.5

Wandering Mystery Planets
NASA Science News for June 29, 2001
The word 'planet' comes from the Greek word 'wanderer,' but the planets in
our solar system aren't true nomads. They stay close to home, always
circling the Sun. This week scientists using the Hubble Space Telescope
may have discovered a class of genuine planetary wanderers. It seems that
mysterious objects smaller than Jupiter are running loose in globular
cluster M22! Are they planets? No one knows, but astronomers are
planning to find out.

Strange glows on Jupiter moon
The white dots seen near the equator are volcanoes
By BBC News Online science editor Dr David Whitehouse
Strange glows have been seen dancing over Jupiter's moon Io. They were
recorded during an eclipse of Io in January, witnessed by the Cassini
spacecraft that was on its way to Saturn.
Cassini's camera captured images of the eclipsed Io in several
colours, ranging from the near-ultraviolet to the near-infrared.
The colour of the diffuse glows tells scientists what elements are
responsible; oxygen and sulphur are the best candidates.
Some of the glows are associated with volcanic eruptions; others are
auroral in nature being caused by Jupiter's titanic magnetic field
wafting over the tiny moon.

Astronomers Find Solar System Body
By ANDREW BRIDGES, AP Science Writer
LOS ANGELES (AP) - Astronomers announced Monday they have discovered
an icy body that rivals Pluto's moon in size and hints that other
planets may lurk within the far reaches of our solar system.
The object, 2001 KX76, appears to be between 595 and 788 miles across,
making it larger than any known asteroid and, perhaps, even Pluto's
moon Charon. Charon is estimated to be 744 miles in diameter.
A team of astronomers used the Cerro Tololo Inter-American Observatory
in Chile to find the object in images taken on May 22. It orbits the
sun at a distance of about 4 billion miles in the Kuiper Belt of
objects beyond Neptune.
The new object apparently trumps in size all other known objects
beyond the orbit of Neptune, except Pluto itself.

Varuna points way to 10th solar planet
PARIS: A large asteroid, named Varuna after the lord of the cosmos in
Hindu mythology, has been spotted in the outer fringes of the Solar
System, a discovery which suggests the Sun may have more than nine
planets, astronomers say.
Varuna was detected last November by Arizona-based astronomers in the
Spacewatch Project, a scheme aimed at scouring the asteroid belts to
look, in part, for rogue rocks that could be a potential threat to
Earth.
The spherical object is 900 km in diameter, which makes it only a tad
smaller than Charon, the tiny moon that orbits Pluto, the most distant
of the Sun's nine known planets.
The discovery, by a team led by David Jewitt of the Institute of
Astronomy in Honolulu, is reported last week in Nature, the British
science weekly.

Howdy all
One of the cool things about meteor showers is that it provides
yet another propagation mode for VHF and up (somewhat). This
is in the form of meteor scatter where you bounce signals off
the ionized particles in the upper atmosphere - the trick here
is that you only have a small window of time to send a signal
since the 'mirror' does not last that long. Most if not all
meteor contacts use time slots for stations to transmit and
receive and it might take several slots to make a contact.
Another, even more exotic mode, is high speed meteor scatter
where you send a burst of data off the ionized air. The
basic contact calls for high speed cw (possibly voice?)
and the burst mode is a cw message speed up superfast and
sent via computer. Ive only tried a meteor contact once on
voice since my cw is not quite what it used to be. I did
hear a brief voice burst from the station I was trying to contact
1200 miles away. Neat stuff but Im busy with enuf distractions
right not to take up another facet of the hobby.

Cosmic One, you need not tell me. My father (W2CWR) had me climbing trees with antennas and doing sightings out the window with a makeshift telephone rig he had hooked up to synchronize the meteors and his reception of the sound. We did it with Aurorae too...
Fantastic about the satellite stuff being up and running again. Meteors are a lot smaller things to aim at than EME transmissions, but are they basically the same? It's all in the timing! And precision aiming of the antennas....and so on and so forth. This is not easy stuff gang!

Aphelion Away! Earth is far from the Sun on the 4th of July
On the 4th of July, Earth will lie at its greatest distance from the Sun
-- an annual event astronomers call 'aphelion.' But don't expect any
sudden relief from the heat. Indeed, say researchers, our planet is
actually warmer when we're farther from the Sun than at any other time of
year -- an earth science curiosity that this story explains.

SOLAR and SPACE WEATHER (July 9, 2001)
3-Day Solar Forecast
Solar activity is expected to be low. But Sunspot Region 9531, which was numbered over the weekend and has been growing rapidly, is a likely source of additional low-level (C-class) solar flares.
3-Day Aurora Forecast
Earth's geomagnetic field is expected to be mainly quiet to unsettled for the next three days. Isolated active periods may also occur as the speed of the solar wind fluctuates.
Solar Data
The current sunspot number is 101, and the solar wind speed recently clocked in at 416 kilometers per second (930,563 mph). The solar wind density was 5.3 protons per cubic centimeter. (Speed and density values are snapshots in time and change during the day.)

sweep (estimated shock velocity 515 km/sec - preliminary), and a strong loop
prominence on the southeast limb. In addition, an interesting and h-alpha
wave is visible propagating onto the visible solar disk to the northwest of
the flaring center. Although this is well time correlated with the presumed
onset of the flare start, it may be an independent phenomena as opposed to a
Moreton-type wave related directly to the flaring site. Nevertheless, it is
interesting to speculate.
The x-ray and radio signatures of this event suggest it was a probable
proton producing flare. However, no significant flux enhancements are
expected in the near-Earth space environment due to its present poor
location. X-ray fluence with this event was modestly respectable at near
0.75 Joules.
The southeast limb has been teeming with activity. Frequent and
occasionally fairly strong surging has been observed over the last 24 hours.
Additional major levels of solar flare activity are expected from this spot
complex as it continues to approach and (within the next 24 to 48 hours)
rotate into view.
Region 10036 is still considered a possible site for major flaring. It
has experienced renewed growth over the last 24 hours. Although magnetic
gradients and shear are not as strong as in Region 10030, the spot complex
may still produce an isolated major event over the next several days. Flare
activity from Region 10036 is expected to be fairly infrequent unless more
rapid growth and dynamic flux emergence occurs. It is expected to take a back
seat to the activity in the region due to rotate around the southeast limb.

Hi all - now this sounds like extreme moonbounce!
73 de Mike
From the ARRL web page
Amateurs Invited to Listen for Radio Signals Bounced Off Asteroid (Aug 15, 2002) -- Amateur Radio operators have been invited to listen in as scientists bounce radio signals off an asteroid that's about to make a "flyby" of Earth. The so-called 2002 NY40 asteroid will come close enough to Earth that it will be visible to sky watchers using binoculars. But because asteroids reflect but a tiny fraction of the light that strikes their surface, a team at the Arecibo Radio Observatory in Puerto Rico will attempt to "ping" the satellite with radio signals as it approaches Earth.
"We will be transmitting about 900 kW with 73 dB of gain towards the
asteroid," Mike Nolan of the Arecibo Radio Observatory told ARRL. "The
transmitted signal will be such that the received signal comes back centered
at 2380.0000000 MHz at the ground station we're aiming for--usually either
Arecibo or the Green Bank Telescope." Nolan said the signal would be either
CW or phase-coded at a bandwidth of up to 20 MHz. "We will be transmitting
most of the time when the asteroid is within 20 degrees of zenith at Arecibo
on August 15-20."

I recall their mentioning that a backward look at Pluto would be the last they expected to hear from Voyager.

* The Migrating Boreal Forest
http://earthobservatory.nasa.gov/Study/BorealMigration/
Since the last ice age, forest species across North America have migrated back and forth across the continent. At one point cold-adapted species such as spruce lived as far south as the Gulf Coast. Comapred to past climate fluctations, current warming is happening very rapidly, and modern forests may be unable to migrate or adapt fast enough to keep up. Large nature reserves that encompass different climatic zones may increase forests' genetic diversity and increase the chances that forest species can adapt and migrate in response to cliamte change.
* Fish Kill in the Gulf of Oman
http://earthobservatory.nasa.gov/Study/oman
When fish began dying in droves off the coast of Oman, local media reported it was due to contaminated ballast water from a U.S. tanker while authorities feared that a toxic algal bloom was to blame. Neither was true. Using data from NASA's Terra and SeaWinds missions, a team of scientists demonstrated the fish kill was due to a series of natural environmental changes.

21 August 2002
02:00 UTC (10 pm EDT)
HEADS UP! AURORA MAY BE VISIBLE IN NORTH AMERICAN MIDDLE LATITUDES
Auroral activity is becoming visible across many middle latitude regions
at the time of this writing - for North American observers. The latest
unconfirmed sighting is from New Hampshire, reporting brief tall rays and a
diffuse glow to the north.
A middle latitude auroral activity watch was issued several hours ago,
but a posting here was held off until we could ascertain that conditions
would hold up. It appears the Earth is imbedded in a stable solar wind stream
capable of producing enhanced substorm activity. This disturbance is related
to another coronal mass ejection disturbance thought to have originated from
active sunspot complex 10069.
Happy hunting!
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
MIDDLE LATITUDE AURORAL ACTIVITY WATCH
WATCH ISSUED: 20:30 UTC, 20 AUGUST 2002
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
VALID BEGINNING AT: IMMEDIATELY
VALID UNTIL: 19:00 UTC (3 pm EDT) ON 21 AUGUST
HIGH RISK PERIOD: 20 AUGUST (UTC DAYS)
MODERATE RISK PERIOD: 20-21 AUGUST
PREDICTED ACTIVITY INDICES: 25, 15, 14, 12 (21 AUGUST - 24 AUGUST)
POTENTIAL MAGNITUDE OF MIDDLE LATITUDE AURORAL ACTIVITY: LOW TO MODERATE
POTENTIAL DURATION OF THIS ACTIVITY: MAIN BELT = 12 HOURS
MINOR BELT = 12 TO 24 HOURS
ESTIMATED OPTIMUM OBSERVING CONDITIONS: NEAR LOCAL MIDNIGHT
EXPECTED LUNAR INTERFERENCE: MODERATE
OVERALL OPPORTUNITY FOR OBSERVATIONS FROM MIDDLE LATITUDES: FAIR TO POOR
AURORAL ACTIVITY *MAY* BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
WASHINGTON STATE TO IDAHO TO NORTHERN WYOMING TO SOUTH DAKOTA TO NORTHERN
IOWA TO NORTHERN ILLINOIS TO NORTHERN INDIANA TO NORTHERN OHIO TO
PENNSYLVANIA TO DARK-SKY SITES OF NEW JERSEY.
ACTIVITY *MAY* ALSO BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
ENGLAND TO NORTHERN BELGIUM TO NORTHERN GERMANY TO NORTHERN POLAND TO
LITHUANIA TO SOUTHERN LATVIA TO NORTHERN RUSSIA. NEW ZELAND AND EXTREME
SOUTHEASTERN REGIONS OF AUSTRALIA MAY ALSO OBSERVE PERIODS OF ACTIVITY.
SYNOPSIS...
A second very mild shock presumeably from activity associated with
Region 10069, arrived at the Earth near 15:48 UTC on 20 August. The
disturbance started out with a northward turning of the IMF. However, over
the last 2 hours, the IMF has swung toward a more southward orientation.
Isolated moderate to strong high latitude substorming is currently being
observed. These conditions may provide some dark-sky middle latitude
observers with a chance to glimpse periods of auroral activity over the next
12 hours - provided solar wind conditions remain favorable.
This watch will remain valid through 19:00 UTC (3 pm EDT) on 21 August.
It will then be updated or allowed to expire. For updated information, visit:
http://www.spacew.com/aurora/forum.html
PLEASE REPORT OBSERVATIONS OF AURORAL ACTIVITY TO:
http://solar.spacew.com/submitsighting.html
Observations reported here are permanently recorded for future study and
are immediately made available in real-time to a large network of observers
world-wide via the Internet, e-mail and pager. If you observe activity, your
assistance to contribute to this database would be appreciated.
A FREE trial of the space weather "SWIM" software package is now
available at: http://www.spacew.com/swim. Use it to monitor current
conditions. It may also be used to monitor any image resource you find on the

PLUTO EVENTS PERPLEX ASTRONOMERS
The last two months have been good ones for Plutophiles. In July a U.S.
Senate subcommittee fortified NASA's budget with $105 million to continue
work on the New Horizons mission, which could be launched toward the
distant planet as soon as 2006. And during the past five weeks telescopes
have captured the passage of Pluto in front of not one, but two faint
stars. Although analysis of the stars' brief disappearances has only
begun, it is already clear that observing teams from the United States and
Europe have come to very different conclusions about the state of Pluto's
atmosphere.
During the first event, on July 20th (Universal Time), Pluto's shadow
crossed South America and, unfortunately, barely missed passing over a
string of major observatories in the Andes. The only "hits" came from
astronomers with portable setups: Marc Buie and Oscar Saa used a 14-inch
Celestron and a CCD camera near the small Chilean town of Mami�a, while
Francois Colas had a video-equipped 12-inch telescope a little farther
north near Arica. According to Bruno Sicardy, who coordinated the European
effort, seven other ground teams in Chile, Ecuador, Peru, and Venezuela
were either clouded out or experienced technical difficulties. Fortunes
improved for the August 21st occultation, as the broad path passed over
observatories in Hawaii and the Far West....

Physics) pointed the Chandra X-ray Observatory at Mars and obtained the
first ever X-ray image of our rusty neighbor.
The realization that Mars has a high-energy glow is not surprising. Venus,
Jupiter, Earth, Saturn, and even comets shine (albeit faintly) in X-rays.
And, as with those bodies, the source is fluorescing oxygen atoms. Near
heights of 80 kilometers in the Martian atmosphere, solar-wind particles
strike oxygen atoms with enough energy to tear away their electrons. But
these ions soon recombine with other electrons and return to their
original, unexcited state, emitting X-rays in the process....

ASTEROID FLYBY SEEN WORLDWIDE
From Uzbekistan and the Crimea to the UK, across North America, and on to
Hawaii, amateur astronomers around the world had fine views of the close
flyby of asteroid 2002 NY40 during the evening of August 17-18, 2002.
The experience of David Nance (Huntsville, Alabama) was typical of the
many reports received at Sky & Telescope. He wrote: "I found 2002 NY40
easily and followed it for about 30 minutes. It was very bright (I'd
estimate it at magnitude 9.5), and it was really spectacular sailing
through the eyepiece, changing the patterns I formed with it and the
framework of stars. My wife thought it was neat since it was so obviously
not a 'fixed' star ... it looked a lot like a slow moving satellite on a
really weird trajectory...."

CONTOUR'S FATE LOOKS "BLEAK"
Although efforts to reestablish contact with the Contour spacecraft
continue, mission managers now suspect that the craft was destroyed during
a rocket firing on August 15th. Convincing evidence came from images
acquired by the Spacewatch telescope about 20 hours afterward, showing two
objects separated in the sky by about 460 kilometers and located some
460,000 km from Earth....
Mission mananger Robert W. Farquhar and his team received the Spacewatch
image in response to a call to professional and amateur astronomers to
help locate the spacecraft. The image shows a pair of 18th-magnitude
objects, one approximately three times brighter than the other. According
to David W. Dunham, head of the mission-design team, the objects were then
within 0.6 degrees of where Contour would have been if on its correct
interplanetary trajectory, and their positions suggest that Contour's
solid-fuel STAR-30 rocket motor provided about 3 percent less total thrust
than expected. Dunham estimates that "Contour A" and "Contour B" are
moving apart at roughly 6 meters per second (14 miles per hour). It is not
yet clear what the two pieces might be. "The spacecraft was built around
the STAR motor," Dunham notes, "and they weren't supposed to separate...."

Sun gives up secrets
The huge ejections contain twisted solar material
The Sun spits out huge bubbles of super-hot electrified gas.
The solar eruptions blast out into space at speeds thousands of times faster than Concorde.
Sometimes they can even disrupt the Earth's magnetic field, leading to power black-outs.
They are also behind the most dramatic spectacle in the sky - the northern (and southern) lights.
The colourful light shows happen when solar eruptions strike the region of space shielded by our planet's magnetic field.
But despite their impact on Earth, it is not known exactly how the Sun spews out the giant bubbles of gas, known as coronal mass ejections (CMEs).
Now UK astrophysicists have found new clues. They think twisted magnetic fields deep within our star could be the driving force.
The evidence comes from data gathered by the SOHO and Yohkoh satellites.
Twisted structures
Twists within the Sun's magnetic field were studied by a team at the Mullard Space Science Laboratory (MSSL) in Surrey.
One theory is these twisted structures are caused by the Sun rotating faster at the equator than the poles, says Dr Lucie Green of MSSL.
But the new study, carried out with colleagues in France and Argentina, suggests a second option is more likely.
"The magnetic field doesn't get twisted enough by the differential rotation that happens on the surface," Dr Green told BBC News Online.
"The implication is that the magnetic field must get twisted deep within the Sun itself."
Scientists hope it will one day be possible to predict when the Sun is likely to emit CMEs as part of space weather forecasts.
"Prediction of space weather is still a long way off but our research is helping us understand why CMEs happen in the first place," says Dr Green.

More aurora for us to hunt for:
Aurora Alert: Saturday, Sept. 7th
Space Weather News for Sept. 7, 2002
http://www.spaceweather.com
AURORA WARNING: A solar wind shock wave swept past Earth on Sept. 7th at
approximately 1630 UT (12:30 EST). The interplanetary magnetic field
turned sharply south when the wave arrived, which means a geomagnetic
storm is likely. Sky watchers in New Zealand and southern Australia, where
it was nighttime when the shock wave struck, have a good chance of seeing
Southern Lights. Observers in northern Europe, and perhaps Canada and
northern US states, might see Northern lights after local nightfall on
Saturday. Stay tuned to spaceweather.com for updates.

A s t r o A l e r t
Sun-Earth Alert
Solar Terrestrial Dispatch
http://www.spacew.com/astroalert.html
07 September 2002
MIDDLE LATITUDE AURORAL ACTIVITY WARNING - 07 SEPTEMBER
A powerful and high velocity coronal mass ejection was observed on 05
September that involved the violent ejection of a solar filament (a string of
cooler gas suspended above the surface of the Sun). The ejection resulted in
a high velocity CME travelling near 1700 km/sec toward the southeast of the
Earth. However, a portion of the CME was also Earthward directed.
The leading edge of this coronal mass ejection was observed impacting
the Earth near 16:37 UTC on 07 September (12:37 pm EDT). This disturbance has
the potential to drive moderate to strong levels of auroral storming over the
high latitude regions. Middle latitude observers are also expected to observe
some of the activity, particularly observers in Europe and north to central
Russia where the timing of the arrival of this disturbance will probably be
best for them. There is debate as to whether the disturbance will last long
enough to produce visible activity by the time night falls for North America.
Nevertheless, observers are encouraged to keep a close eye on the sky and
current conditions.
Current sighting reports are available at:
http://www.spacew.com/www/auroras.html
Current discussion of activity and the latest forecast notes are at:
http://www.spacew.com/aurora/forum.html
*NEW*
A new real-time image publishing server is now operational that will
permit people to publish images of astronomical or aurora events within 1 to
2 minutes of submitting them. This is an ideal avenue to publish images of
observed activity in near real-time so others can see what you are seeing, or
to showcase your own images in real-time. Details and instructions on how to
use the new service are available at: http://www.spacew.com/gallery/help.html.
The Gallery itself can be found at:
http://www.spacew.com/gallery
The official mid-latitude auroral activity warning report is included
below:
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
MIDDLE LATITUDE AURORAL ACTIVITY WARNING
UPDATED: 16:30 UTC, 07 SEPTEMBER 2002
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
*** DISTURBANCE ARRIVAL ALERT ***
*** POTENTIAL FOR MODERATE TO HIGH ACTIVITY EXISTS ***
For North Americans, begin watching TONIGHT, the evening of 07 September.
VALID BEGINNING AT: EFFECTIVE IMMEDIATELY
VALID UNTIL: 19:00 UTC ON 08 SEPTEMBER
HIGH RISK PERIOD: 07 SEPTEMBER (UTC DAYS)
MODERATE RISK PERIOD: 07 - 08 SEPTEMBER
PREDICTED ACTIVITY INDICES: 35, 20, 12, 12 (07 SEP - 10 SEP)
POTENTIAL MAGNITUDE OF MIDDLE LATITUDE AURORAL ACTIVITY: MODERATE TO HIGH
POTENTIAL DURATION OF THIS ACTIVITY: MAIN BELT = 12 TO 18 HOURS
MINOR BELT = 18 TO 24 HOURS
ESTIMATED OPTIMUM OBSERVING CONDITIONS: NEAR LOCAL MIDNIGHT
EXPECTED LUNAR INTERFERENCE: NONE
OVERALL OPPORTUNITY FOR OBSERVATIONS FROM MIDDLE LATITUDES: FAIR TO GOOD
AURORAL ACTIVITY *MAY* BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
OREGON TO SOUTHERN IDAHO TO EXTREME NORTHERN UTAH TO SOUTHERN WYOMING TO
NEBRASKA TO IOWA TO NORTHERN ILLINOIS TO INDIANA TO OHIO TO NORTHERN
VIRGINIA AND MARYLAND.
ACTIVITY *MAY* ALSO BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
EXTREME NORTHERN FRANCE TO BELGIUM TO CENTRAL GERMANY TO CENTRAL POLAND TO
BELARUS TO CENTRAL RUSSIA.
SYNOPSIS...
A moderately strong interplanetary shock was observed passing the ACE
spacecraft near 16:18 UTC (12:18 pm EDT) on 07 September. The disturbance has
good characteristics that are expected to help drive periods of intensified
auroral storm activity. Middle latitude observers are encouraged to keep a
close eye on conditions. European and Russian observers will be
optimally placed for observing activity. There is some doubt as to whether
the activity will remain strong enough to permit widespread middle latitude
sightings by the time North America sees darkness. Keep a close eye on
current conditions by visiting: http://www.spacew.com/aurora/forum.html and
http://www.spacew.com/www/auroras.html where reports of activity will be
displayed. The new phase of the moon will allow unrestricted and optimal
observations of activity under dark skies - ideal conditions for observing
the intricate details of auroral activity.
This warning will remain in effect until 19:00 UTC on 08 September. It
will then be updated or allowed to expire.
Please note that a new real-time aurora image gallery is available for
public use at: http://www.spacew.com/gallery. This service is capable of
publishing imagery within 1 to 2 minutes of the receipt of the images. As a
result, it is an ideal way for people to show others what they are seeing. If
you have a digital camera and are able to take a snapshot of auroral
activity, send your image to the gallery so other's who may be less fortunate
can observe what you are seeing. If you are taking pictures with film, please
feel free to submit your images after you have developed your film.

Research Uncovers New Kuiper Belt Mystery
Although the Kuiper Belt, a region of icy objects located past the orbit of Neptune, was only discovered in 1992, it's already presented a host of mysteries. One mystery is why an unusually large number of these objects have small satellites orbiting them - 8 out of the 500 objects discovered so far have had satellites. The high number brings into question the traditional theory that they're caused by collisions.

An article about medium sized objects that might hit the earth.
"Small meteors more likely to leave deadly
trail of destruction on Earth, scientists say
By STEPHEN STRAUSS
Friday, November 22, 2002 � Page A21
Anyone who has ever been frightened by the Hollywood movie concept of an
asteroid smashing into Earth can rest a little easier because of
Canadian-led research published yesterday.
Scientists have used previously secret U.S. military satellite data to
estimate that a destructive impact will occur an average of once every
1,000 years. Previous estimates had suggested that an asteroid could
strike once every 200 to 300 years.
"Most of our attention has focused on the bigger guys which can cause
global damage, but the mean time of them occurring is about 700,000 years.
However, the smaller guys can cause significant regional damage and do it
much more often," said Peter Brown, an astronomer at the University of
Western Ontario in London, who is the lead author of a new paper on the
subject published in yesterday's issue of the journal Nature.

Ancient, Frozen Antarctic Life Revived, Along with Hopes for Life on Mars
By Robert Roy Britt
Senior Science Writer
16 December 2002
Within ice that covers a salty, liquid Antarctic lake scientists have found and revived microbes that were at least 2,800 years old. The discovery, announced today, points to probable life within the underground lake and suggests the sort of ecosystem that might exist on Mars.
The ancient microbes were in a state of suspended metabolism, similar to dormancy, said study team member John Priscu of Montana State University.
"They're in a frozen state," Priscu said in a telephone interview. "They'll come back to life if you add water."
Priscu and his colleagues camped out on the ice above 2.5-mile-long (5-kilometer) Lake Vida for about two weeks back in 1996. They drilled down about 50 feet (15 meters) to collect the aged bacteria. They were just reaching the briny slush of the lake, said to be seven times saltier than the ocean and able to remain liquid even at temperatures lower than -10 Celsius (14 degrees Fahrenheit).
"It was hard drilling," Priscu said. "It was 40 below. It was a real tough job. The next step was to get to the brine."
However, to prevent contaminating the pristine lake, the drilling system was back-pressured with de-ionized water. Seals began to fail, and the system started to leak. The researchers were forced to stop.
Priscu thinks the lake holds live organisms. Life has been found in similar salty conditions, such as the Great Salt Lake and the Dead Sea. And his lab work shows organisms can thrive in the frigid temperatures presumed for Lake Vida. His team has frozen blocks of organisms to -15 Celsius and kept them alive.
Confidence for life on Mars
Further, he said similar pockets of ice or briny water on Mars almost surely hold life, or at least signs of it. Other researchers are typically more reserved about their speculation of possible life on Mars. But Priscu has seen the living, up close, in the harshest conditions our own planet has to offer.
Critters called cyanobacteria dominate life at these extremes. Another Antarctic Lake, called Vostok, has been under similar study and organisms have been found in the ice above it. And several research teams have examined cyanobacteria in easier-to-reach pockets of polar ice. The creatures are innovative enough to generate their own sunscreen -- a handy ability to have on Mars, where radiation is harsher than on Earth.
The Lake Vida creatures are unique for their age, determined by the age of ice in which they were embedded. Other similar studies have involved ice that is frequently replenished and not as old.
Frozen polar regions on Mars might contain organisms similar to those Priscu and his colleagues have been studying over the years, he said. Or deep underground pockets of ice -- or even water -- could support them. In Priscu's mind, the question of finding life on Mars is only whether it will be crawling around or hung in a sort of natural ice museum.
"It's either extinct or extant," he said, alliteratively ruling out the possibility of coming up entirely empty in the search for past or present life on the Red Planet.
Just thaw them out
He said data his team has collected suggest bacteria and their DNA can remain viable for up to a million years. Ice is a good preservative, he said. Add a little water -- which even in a deep freeze can occur in layers where frictional energy melts ice for brief periods -- and organisms might maintain and repair their blueprints for life for many millions of years.
"If they're frozen [on Mars] and younger than 1 million years," Priscu said, "give them some water and they probably would come back."
The research, funded by the National Science Foundation and NASA, is reported in the Dec. 16 issue of the Proceedings of the National Academy of Sciences.
Peter Doran of the University of Illinois at Chicago is the lead author of the paper.
When the study began, the scientists had thought Lake Vida might be a frozen chunk of ice, like other known "lakes" in the region. But the ice cores, along with ground-penetrating radar and long-term temperature data, revealed that Vida has a thick, light-blocking ice cover, vast amounts of ancient organic material and sediment, and the liquid zone underneath.
"Mars is believed to have a water rich past, and if life developed, a Lake Vida-type ecosystem may have been the final niche for life on Mars before the water bodies froze solid," Doran said in a statement.

SHUTTLE COLUMBIA ROCKETS INTO ORBIT FOR SCIENCE FLIGHT
------------------------------------------------------
With fighter planes and radars scanning the sky for intruders, the shuttle Columbia thundered away on a marathon 16-day science mission Thursday, carrying a crew of seven - including the first Israeli astronaut - scores of experiments and a menagerie of animal and insect research subjects.

Ask yourself, what would really get Marci's juices going?
Answer: a news story that combines space and volcanoes.
At the edge of space � the same cold region where space shuttle Columbia broke up into a trail of debris � shiny, silvery blue clouds have been hovering.
The high-altitude ice clouds are called noctilucent or "night-shining" clouds, and astronauts as well as Earth-bound scientists have been puzzled by their growing abundance.
The clouds are visible from space and from the ground over areas that are experiencing summer weather. Astronauts on the space station are seeing them over the southern hemisphere where it's now warm.
"We've seen definite changes," said John Olivero, a professor of physical science at Embry-Riddle Aeronautical University in Daytona Beach, Fla. "It appears the particles that make up the clouds have gotten slightly bigger with time and it appears the clouds are now visible further away from the poles than they have been before."
Volcanic Beginning
The last time these high, shiny clouds appeared in great numbers was after the 1883 eruption of the island volcano, Krakatoa, in Indonesia. The explosion hurled plumes of ash up to 50 miles into the air and caused spectacular sunsets.
The ash particles also served as rare anchors to water vapor at high altitudes and the vapor condensed to ice, forming the brilliant blue clouds. Sky gazers who stayed up late following the eruption reported seeing wispy, glowing streaks in the night sky. Before this incident there were no reported sightings of noctilucent clouds.
But why so many night shining clouds now?
"It's still being debated," says Chester Gardner, an atmospheric scientist at the University of Illinois at Urbana.
One reason scientists are having such a hard time understanding the shimmering clouds is their location. At 30-60 miles above Earth, the mesosphere is also known as the "ignorosphere" due to its inaccessibility. The region is too far to reach by weather balloon and yet it sits below where orbiting satellites or other craft might orbit because its heavier atmosphere would cause too much drag.

Busy Sky: Jupiter, Mars and Comet NEAT
Space Weather news for March 8, 2003
http://www.spaceweather.com
MARS: Mars and Earth are converging for an extraordinary close encounter
later this year. The approaching red planet is now brighter than a
1st-magnitude star--it's gliding through the star fields of Sagittarius in
the morning sky.
JUPITER: The brightest "star" in the evening sky is Jupiter. This month
the giant planet is gliding by the Beehive Cluster of stars in the
constellation Cancer. The view through binoculars is splendid!
COMET NEAT: After a close encounter with the Sun last month, Comet NEAT
is emerging from the Sun's glare into the evening skies of the southern
hemisphere. Sky watchers in Argentina, Australia and New Zealand (among
other places) say the comet is dim yet visible to the unaided eye with a
tail that looks nice through small telescopes and binoculars.
AURORAS: Solar wind gusts buffeted Earth's magnetic field last week and
sparked auroras at high latitudes. The next series of geomagnetic storms
could begin around March 15th.

From NASA science news:
From Feb. 4th, 2003: At the dawn of the space age some 40 years ago, we always
knew who was orbiting Earth or flying to the Moon. Neil Armstrong, Yuri
Gagarin, John Glenn. They were household names--everywhere.
Lately it�s different. Space flight has become more �routine.� Another
flight of the shuttle. Another visit to the space station. Who�s onboard
this time? Unless you�re a NASA employee or a serious space enthusiast,
you might not know.
Dave Brown, Rick Husband, Laurel Clark, Kalpana Chawla, Michael Anderson,
William McCool, and Ilan Ramon
Now we know. Those are the names of the seven astronauts who were
tragically lost on Saturday, Feb. 1st, when the space shuttle Columbia
(STS-107) broke apart over Texas.
Before the accident, perhaps, they were strangers to you. But if that's
so, why did you have a knot in your gut when you heard the news? What were
those tears all about? Why do you feel so deep-down sad for seven
strangers?
Astronauts have an unaccountable hold on us. They are explorers. Curious,
humorous, serious, daring, careful. Where they go, they go in peace. Every
kid wants to be one. Astronauts are the essence of humanity.
They are not strangers. They are us.
While still in orbit Dave Brown asked, jokingly, �do we really have to
come back?�
No. But we wish you had.
The Science@NASA team, as does all of NASA and the world, extends
heartfelt sympathies to the family, friends and colleagues of the STS-107
crew. Please see the NASA Home Page (http://www.nasa.gov) for more
information on the Columbia Investigation.

Delay to US Mars mission
By Helen Briggs
BBC News Online science reporter
The US space agency Nasa has been forced to delay the launch of the first of the two rovers it is sending to Mars this summer.
The take-off has been put back by a week or so to allow electrical repairs to be made to the identical rovers.
The rover will act as a 'robot geologist'
Pre-launch tests at the weekend raised concerns that they might be vulnerable to a computer glitch.
The spacecraft will now have to be taken apart at Nasa's Kennedy Space Center in Cape Canaveral, Florida.
George Diller of the Kennedy Space Center said an electrical circuit board needed to be modified.
"It'll be a fairly easy thing to fix but it does mean going into both of the rovers, removing the circuit card and making some modifications to it," he told BBC News Online.
The first Mars Exploration Rover was set to be launched by a Delta 11 rocket on 30 May.
It will now take off between 6 June and 19 June. The second spacecraft will be launched 10 days after the first.

Talking shop was what I wanted out of them, but instead they ended up picking my brains about what was edible on the "exotic" Japanese dinner buffet. This was pre-sushi days, so the thought of eating seaweed and raw fish scared them to death. They would go the moon strapped to a firecracked, but NOT eat weird food. One noticed a big bowl of eggs. He commented that at least they knew how to eat hard boiled eggs! I hated to tell them, but those eggs were also raw! Used to cool off blistering hot soups, they end up like thin scrambled eggs. It was great fun. We talked about all sorts of things. I wondered to them if the constellations were as hard to define from 35,000 feet as it was beyond. I never heard the answer.

A 53-hour Chandra observation of the central region of the Perseus galaxy
cluster (left) has revealed wavelike features (right) that appear to be
sound waves. The features were discovered by using a special
image-processing technique to bring out subtle changes in brightness.
Illustration of Ripples in Perseus
These sound waves are thought to have been produced by explosive events
occurring around a supermassive black hole (bright white spot) in Perseus
A, the huge galaxy at the center of the cluster. The pitch of the sound
waves translates into the note of B flat, 57 octaves below middle-C. This
frequency is over a million billion times deeper than the limits of human
hearing, so the sound is much too deep to be heard.
The image also shows two vast, bubble-shaped cavities, each about 50
thousand light years wide, extending away from the central supermassive
black hole. These cavities, which are bright sources of radio waves, are
not really empty, but filled with high-energy particles and magnetic
fields. They push the hot X-ray emitting gas aside, creating sound waves
that sweep across hundreds of thousands of light years.
Animation of Sound Waves Generated in Perseus Cluster
The detection of intergalactic sound waves may solve the long-standing
mystery of why the hot gas in the central regions of the Perseus cluster
has not cooled over the past ten billion years to form trillions of stars.
As sounds waves move through gas, they are eventually absorbed and their
energy is converted to heat. In this way, the sound waves from the
supermassive black hole in Perseus A could keep the cluster gas hot.
The explosive activity occurring around the supermassive black hole is
probably caused by large amounts of gas falling into it, perhaps from
smaller galaxies that are being cannibalized by Perseus A. The dark blobs
in the central region of the Chandra image may be fragments of such a
doomed galaxy.

And get this, from the article.
Get this...
The sun sends out a stream of highly charged particles, called the solar
wind, that carves out a vast bubble around the solar system.
Beyond the bubble's ever-shifting boundary, called the termination shock,
lies a region where particles cast off by dying stars begin to hold sway.
That region, called the heliopause, marks the beginning of interstellar
space and the end of our solar system. Whether Voyager 1 reached that mark
or is still on approach remains unclear, with scientists providing
evidence for both claims. Details appear Thursday in the journal Nature.
"Neither explanation is certain," writes Len Fisk, of the University of
Michigan, in an editorial accompanying the two studies.

Scientists have long theorized that a shock wave exists where the hot
solar wind bumps up against the thin gas of the interstellar medium. A
similar shock wave precedes aircraft flying faster than the speed of
sound, causing a sonic boom.
In space, the violent encounter slows the solar wind from supersonic
velocity to subsonic speed, and causes a pileup of particles.
As they accumulate, the particles increase in temperature. Also, as they
skip back and forth across the shock boundary, they are accelerated and
energized.
Scientists have pored over data from Voyager 1 for evidence of any of
those activities, which would suggest the one-ton spacecraft has reached
the termination shock. The one instrument that could measure the solar
wind velocity and give somewhat of a definitive answer ceased working
years ago.
One team, studying lower energy particles, inferred that the solar wind
velocity did tail off beginning in August 2002, suggesting Voyager 1
temporarily reached the termination shock.

This true color mosaic of Jupiter was constructed from images taken by the
narrow angle camera onboard NASA's Cassini spacecraft on December 29,
2000, during its closest approach to the giant planet at a distance of
approximately 10 million kilometers (6.2 million miles).
It is the most detailed global color portrait of Jupiter ever
produced; the smallest visible features are approximately 60
kilometers (37 miles) across. The mosaic is composed of 27 images: nine
images were required to cover the entire planet in a tic-tac-toe pattern,
and each of those locations was imaged in red, green, and blue to provide
true color. Although Cassini's camera can see more colors than humans
can, Jupiter's colors in this new view look very close to the way the
human eye would see them.
Everything visible on the planet is a cloud. The parallel reddish-brown
and white bands, the white ovals, and the large Great Red Spot persist
over many years despite the intense turbulence visible in the atmosphere.
The most energetic features are the small, bright clouds to the left of
the Great Red Spot and in similar locations in the northern half of the
planet. These clouds grow and disappear over a few days and generate
lightning. Streaks form as clouds are sheared apart by Jupiter's intense
jet streams that run parallel to the colored bands. The prominent dark
band in the northern half of the planet is the location of Jupiter's
fastest jet stream, with eastward winds of 480 kilometers (300 miles) per
hour. Jupiter's diameter is eleven times that of Earth, so the smallest
storms on this mosaic are comparable in size to the largest hurricanes on
Earth.
Unlike Earth, where only water condenses to form clouds, Jupiter's clouds
are made of ammonia, hydrogen sulfide, and water. The updrafts and
downdrafts bring different mixtures of these substances up from below,
leading to clouds at different heights. The brown and orange colors may be
due to trace chemicals dredged up from deeper levels of the atmosphere, or
they may be byproducts of chemical reactions driven by ultraviolet light
from the Sun. Bluish areas, such as the small features just north and
south of the equator, are areas of reduced cloud cover, where one can see
deeper.

Solar maximum is years past, yet the sun has been remarkably active
lately. Is the sunspot cycle broken?
FULL STORY at
http://science.nasa.gov/headlines/y2003/12nov_haywire.htm?list89800
*****************
A RECORD-BREAKING SOLAR FLARE & MID-LATITUDE AURORA WATCH
At approximately 19:47 UTC (2:47 pm EST) on 04 November, active sunspot
complex 10486 spawned what is probably the most intense x-ray flare in
history. X-ray sensors on-board the GOES spacecraft are only capable of
registering x-ray intensities up to a class X17.4 level. X-ray intensities
beyond this level saturate the detectors. This solar flare saturated the
x-ray detectors for 11 minutes, leaving space weather forecasters and
scientists with some work to try and extrapolate the true intensity of the
event. Based on a preliminary extrapolation, it appears that this x-ray flare
peaked somewhere between the X30 and X40 levels, which was unheard of until
yesterday and is possibly as much as twice as energetic as the X17 solar
flare observed on 02 November.
To place this event into historic perspective, it very likely ranks as
the most powerful x-ray flare ever observed. During the last two weeks,
active Region 10486 has produced three x-ray flares that have ranked within
the top 10 of the most intense events in history. It has been quite a ride!
Region 10486 has now rotated behind the western limb and out of view. It
will now spend the next two weeks traversing the far side of the Sun. Whether
it survives its passage on the far-side and returns to the eastern limb in
two weeks in a form still capable of producing energetic events remains
unknown. It is possible it could return in a form still capable of producing
energetic events, but the odds are against it.
Although only time will tell, observers on Earth will be able to monitor
its progress indirectly by watching for coronal mass ejections that occur on
the far side of the Sun, but are still visible from Earth via the SOHO LASCO
cameras.
Spectacular imagery of this solar flare and the associated high velocity
coronal mass ejection are available from the SOHO web site:
http://soho.nascom.nasa.gov/hotshots
A movie of the event in the light of hydrogen is also available from:
http://www.spacew.com/x30ha.gif
It is known that yesterdays remarkable solar flare was associated with a
coronal mass ejection. The vast majority of mass thrown out was directed well
to the west of the Earth. However, a small portion was also directed
Earthward. That portion is expected to impact the Earth on 06 November. After
the disturbance arrives, it may be capable of producing periods of minor to
major geomagnetic and auroral storm activity. A disturbance as large as was
observed on 29 and 30 October is not expected. Nevertheless, auroral activity
could become visible from many middle latitude locations. A middle latitude
aurora watch is active for 06 November. For North Americans, that is TONIGHT.
Late tonight, near or after local midnight. Interference from the near-full
moon will hamper attempts to view activity.

SYNOPSIS...
Effects of perhaps the largest x-ray solar flare on record are expected
to impact the Earth sometime near 07:00 UTC on 06 November, give or take
several hours. The solar flare occurred on the western limb of the Sun and as
a result is not expected to produce significant effects at the Earth.
However, the disturbance should have the strength to produce periods of
auroral storming over the high and middle latitude regions.
This watch will remain valid through 23:00 UTC (7 pm EDT) on
07 November. It will then be updated or allowed to expire. Most (if not all)
of the activity is expected to occur within the first 6 to 12 hours after the
disturbance impacts. For this reason, we don't expect very much on 07
November. For updated information, visit:

activity, visit: http://www.spacew.com/plots.html or www.sec.noaa.gov.

DARK MATTER FORMS A GHOST UNIVERSE, NEW THEORY SHOWS
----------------------------------------------------
The "dark matter" that comprises a still-undetected one-quarter of the
universe is not a uniform cosmic fog, says a University of California,
Berkeley, astrophysicist, but instead forms dense clumps that move about
like dust motes dancing in a shaft of light.

TURBULENT NEIGHBORHOOD SEEN NEAR ERUPTIVE STAR
----------------------------------------------
A small portion of the rough-and-tumble neighborhood of swirling dust and

in this Hubble Space Telescope image. This close-up view shows only a
three light-year-wide portion of the entire Carina Nebula, which has a
diameter of over 200 light-years. Located 8,000 light-years from Earth,
the nebula can be seen in the southern sky with the naked eye.

VOYAGER APPROACHING SOLAR SYSTEM'S OUTER LIMITS
-----------------------------------------------
NASA's Voyager 1 spacecraft is about to make history again. It is the
first spacecraft to enter the solar system's final frontier, a vast
expanse where wind from the sun blows hot against thin gas between the
stars: interstellar space.

ROSES IN THE SOUTHERN SKY
-------------------------
The two best known satellite galaxies of the Milky Way, the Magellanic
Clouds, are located in the southern sky at a distance of about 170,000
light-years. They host many giant nebular complexes with very hot and
luminous stars whose intense ultraviolet radiation causes the surrounding
interstellar gas to glow.

PROPOSED NASA EXPLORER MISSIONS SELECTED FOR STUDY
--------------------------------------------------
NASA recently selected candidate mission proposals that would study the
universe, from Jupiter and the sun to black holes and dark matter. The
proposals are candidates for missions in NASA's Explorer Program of lower
cost, highly focused, rapid-development scientific spacecraft.

Dusty disc may mean other Earths
By Dr David Whitehouse
BBC News Online science editor
Astronomers say they have evidence for Earth-like planets orbiting a
nearby star, making it more like our own Solar System than any yet
discovered.
The star, Vega, is one of the brightest in the sky, only 25 light-years
away.
It is three times larger than our Sun and, at 350 million years old, much
younger as well.
Vega has a disc of dust circling it, and at least one large planet which
could sweep debris aside allowing smaller worlds like Earth to exist.

Black holes are raining down on Earth and exploding!
http://uk.news.yahoo.com/031204/12/eg99n.html
Are mini black holes raining down through the Earth's atmosphere? It is
possible, says a team of physicists. They think this could explain
mysterious observations from mountain-top experiments over the past 30
years.
Ordinary black holes form when stars explode at the end of their lives.
The heavy stellar core can collapse into a superdense "singularity" whose
gravity is so strong that nothing - not even light - can escape.
If some of physicists' favourite theories about extra dimensions are
correct, it would also be possible for high-energy cosmic-ray particles
from space to create black holes when they collide with molecules in the
Earth's atmosphere ( New Scientist print edition, 29 September 2001).
These black holes would be invisibly small, with a mass of only 10
micrograms or so. And they would be so unstable that they would explode in
a burst of particles within around a billion-billion-billionth of a
second.

The lander may be shadowed by this crater. It can't power up yet.

Beagle to begin 'frequent calls'
If Beagle is alive, it will call more frequently
British-built Mars probe Beagle 2 is due to switch into a communications
mode on Wednesday that increases the chances of contact being made with
it. If Beagle is intact on the Martian surface, it will automatically
begin "calling" Earth more frequently.
Two further attempts were made on Tuesday to contact Beagle with the Mars
Odyssey craft in orbit around the Red Planet, but with no positive
result.

A traveling robotic geologist from NASA has landed on Mars and returned
stunning images of the area around its landing site in Gusev Crater.
Mars Exploration Rover Spirit successfully sent a radio signal after the
spacecraft had bounced and rolled for several minutes following its
initial impact at 11:35 p.m. EST (8:35 p.m. Pacific Standard Time) on
January 3.
"This is a big night for NASA," said NASA Administrator Sean O'Keefe.
"We're back. I am very, very proud of this team, and we're on Mars."
Members of the mission's flight team at NASA's Jet Propulsion Laboratory,
Pasadena, Calif., cheered and clapped when they learned that NASA's Deep
Space Network had received a post-landing signal from Spirit. The cheering
resumed about three hours later when the rover transmitted its first
images to Earth, relaying them through NASA's Mars Odyssey orbiter.
"We've got many steps to go before this mission is over, but we've retired
a lot of risk with this landing," said JPL's Pete Theisinger, project
manager for the Mars Exploration Rover Project.
Deputy project manager for the rovers, JPL's Richard Cook, said, "We're
certainly looking forward to Opportunity landing three weeks from now."
Opportunity is Spirit's twin rover, headed for the opposite side of Mars.
Dr. Charles Elachi, JPL director, said, "To achieve this mission, we have
assembled the best team of young women and men this country can put
together. Essential work was done by other NASA centers and by our
industrial and academic partners.
Spirit stopped rolling with its base petal down, though that favorable
position could change as airbags deflate, said JPL's Rob Manning,
development manager for the rover's descent through Mars' atmosphere and
landing on the surface.
NASA chose Spirit's landing site, within Gusev Crater, based on evidence
from Mars orbiters that this crater may have held a lake long ago. A long,
deep valley, apparently carved by ancient flows of water, leads into
Gusev. The crater itself is basin the size of Connecticut created by an
asteroid or comet impact early in Mars' history. Spirit's task is to spend
the next three months exploring for clues in rocks and soil about whether
the past environment at this part of Mars was ever watery and suitable to
sustain life.
Spirit traveled 487 million kilometers (302.6 million) miles to reach Mars
after its launch from Cape Canaveral Air Force Station, Fla., on June 10,
2003. Its twin, Mars Exploration Rover Opportunity, was launched July 7,
2003, and is on course for a landing on the opposite side of Mars on Jan.
25 (Universal Time and EST; 9:05 p.m. on Jan. 24, PST).
The flight team expects to spend more than a week directing Spirit through
a series of steps in unfolding, standing up and other preparations
necessary before the rover rolls off of its lander platform to get its
wheels onto the ground. Meanwhile, Spirit's cameras and a
mineral-identifying infrared instrument will begin examining the
surrounding terrain. That information will help engineers and scientists
decide which direction to send the rover first.
JPL, a division of the California Institute of Technology, manages the
Mars Exploration Rover project for NASA's Office of Space Science,
Washington. Additional information about the project is available from JPL

JPL engineers played Bob Marley's "Get Up, Stand Up" in the control room
as they watched new images confirming that the Mars Exploration Rover
Spirit successfully stood up on its lander late Thursday night Pacific
time, a major step in preparing for egress. This image from the rover's
front hazard avoidance camera shows the rover in the final stage of its
stand-up process. The two wheels on the bottom right and left are locked
into position, along with the suspension system. The martian landscape is
in the background.

Spirit rover overloaded with files
http://www.cbc.ca/stories/2004/01/26/mars_rovers040126
Too many data files may have led to the crippling of NASA's Spirit
rover last week, the U.S. space agency said Monday.
Engineers weren't aware the hundreds of the data files would lead to a
major technical difficulty for Spirit. Since Jan. 22, the Mars robot
has been unable to send scientific data and images.
Now that NASA is aware of the limit, the files will be deleted from
Spirit and engineers will take care not to run into the same problem on
its twin, Opportunity, said Jennifer Trosper, mission manager for
operations on Mars' surface.
Problem solved? NASA scientists are giddy!
I found out the Mars day is just about an hour longer than the earth day.
And some folks are downloading "Mars clocks".

*grin* yes, how to confuse the already time-handicapped! Just one planet away and so close to our own time. This does not bode well unless you distinguish that only on Mars is that clock useful!

Hubble finds farthest galaxies
http://www.cnn.com/2004/TECH/space/03/09/hubble.farthest/
Astronomers using the Hubble Space Telescope (HST) unveiled the
deepest look into the universe yet, a portrait of what could be the
most distant galaxies ever seen.
The new image, called the Hubble Ultra Deep Field (HUDF), includes
objects that until now have been too faint to be seen and includes
ancient galaxies that emerged just 700 million years after the Big Bang
theory from what astronomers call the "Dark Ages" of the universe.

Scientist attacks alien claims on Mars
By Robert Roy Britt
SPACE.com
Thursday, March 18, 2004 Posted: 5:25 PM EST (2225 GMT)
Richard Hoagland claims that NASA refuses to acknowledge evidence of alien
"artifacts" on Mars.
SPACE.COM: War of words to debunk aliens
(SPACE.com) -- Astronomer Philip Plait is tired of radio personality
Richard Hoagland's claims.
He's had enough of Hoagland's assertions that NASA is covering up evidence
of extraterrestrial life, that the infamous Face on Mars was built by
sentient aliens and, of late, that otherworldly machine parts are embedded
in the Red Planet's dirt.
And then there's the mile-long translucent martian worm.
On Hoagland's Web site, there are several images from various space probes
said to possibly show evidence for ETs. Recent Mars rover photos include
not just rocks, Hoagland and other contributors maintain, but common
objects that might tell of an alien civilization -- a bowl, a stove, a
piston.

Since 1983, Hoagland said he has led "an outside scientific team in a
critically acclaimed independent analysis of possible
intelligently-designed artifacts" on other worlds, using spacecraft data
from NASA and other missions.
Plait, author of "Bad Astronomy" (Wiley & Sons, 2002), which debunks space
myths and common factual misconceptions, had for years not countered
Hoagland directly, because he did not want to give a man he calls a
"pseudoscientist" the "air time that he so desperately seeks."
But last week Plait took his intellectual gloves off.
