Large Ring Observed on Jupiter (this article is not from sci.astro).
A very large dark ring is seen surrounding the impact site which
moved onto the limb at about 10:02 UT 21 July. (perhaps the L
site?) The ring extended beyond the south pole, and nearly to the
equator, imaged using a Bessell blue filter and CCD detector. The
central impact site was also dark in this filter. Where this ring
intersected Jupiter's dark band at about 20 degrees south latitude
(belt? zone?) the methane image shows a bright spot. The impact site
is not bright in the methane (8900 A, 300 A wide) This complex was
seen to move across the face of the planet in successive images taken
between 9:24 and 10:38 UT. By 12:46 poor seeing prevented seeing it.
This feature was marginally visible in a narrowband sodium filter,
but not in a Cousins R filter. These observations are part of the
Comet Impact Network Experiment headed by Steve Larson of the
University of Arizona.

DrDarkMatter: >Why are the SL9 spots black? 21 Jul 1994 17:43
No one knows the answer yet but here are some possibilities:
1) first of all the spots are only dark at visible wavelengths. In the
IR they appear bright.
2) at visible wavelengths, Jupiters source of light is reflected sunlight.
Jupiter (and Saturn) have relatively high reflectivity due to their upper
cloud deck which consist of materials that have high reflectivity. The
bands visible on Jupiter are called belts and zones. The zones are high,
clouds which are being lifted up via convection. The actual composition
of the clouds is uncertain but they are likely made of Ammonia/Sulfur
compounds or possibly organic molecules. The zones are darker regions where
we are seeing to deeper levels in the atmosphere. These levels are warmer.
3) that upper cloud deck has been seriously modified by this event and so
the high reflectivity components have been destroyed (this is clearly seen
in the UV images from HST which shows the dark regions to be significantly
larger). So the local UV/optical reflectivity may have been greatly reduced.
4) the brightness of the holes in the Infrared also suggests that these holes
are portals down to deeper layers of the atmosphere where the temperature might
be a few 100 hundred degrees Kelvin and thus emit at infrared wavelengths
In sum, the most likely explanation is that the ices which represent the
cloud tops have been locally destroyed so that, at visible wavelengths,
there is just no reflectivity and the spot appears dark.
Note that Voyager measurements suggest a temperature gradient in jupiter
of 2 Kelvins per kilometer.

It is 300 K after it has risen well above the clouds. The surroundings are
probably lower than 100 K, until the plume rises all the way out of the
atmosphere.
The model by Zahnle and Mac Low [1] has the energy release maximum around
the 10-bar level of the atmosphere, at which the ambient temperature is about
300 K. At the 0.5-bar level, T is 120 K (this is about the top of the
ammonia clouds [2]. The value for the initial blast temperature used in the
model was 15,000 K, and that for the wake left by the bolide ranged from
9,000 to 50,000 K. The nominal figure for the explosion is 10^28 ergs (I
don't know that in megatons). Zahnle and Mac Low successfully predicted,
in my opinion, both the explosion (as opposed to fizzle) and the fact that
the fireball would rise out of the atmosphere and have a greater radiative
photon flux than that apparent from Io.

Glen Little: Living on Jupiter during Comet Strikes! 21 Jul 94 09:39
For those interested, there is a great short story that is
set in the clouds of Jupiter. It relates the experiences of
the natives residents of Jupiter (large, winged creatures)
and how they experience and cope with the coming of the comets.
The story seems technically sound and well researched. You
can find it in the July 1994 issue of Analog Science Fiction
and Fact - called "Symphony for Skyfall"...

freshair@shrsys: >The Great Comet Crash - live on PBS Thu, 21 Jul 1994 15:19
>If you are associated with PBS, my congratulations.
Thank you very much....after reading all the flames I was
beginning to get very depressed. A lot of people from very
diverse groups, agencies, etc. worked very hard to pull
together a program that featured cooperation of scientists,
computer specialists, TV producers, technicians, Internet
service providers, university and science museum people....
I suppose it was clearer to us how the convergence of
technology for information distribution was given a small
but important showcase, but it was a step in a direction
that I personally believe is an indication of the future
type of things that media, especially public media can
do.
Yes, it was live....yes, there may have been an awkward
moment or two -- however when I got home, CBS news was
featuring a program about the news coverage of the event
and how even the scientists being asked questions by
a bewildered media got their facts confused at times
and had to correct themselves-- it happens in the
pressure of live TV and we try to avoid it or fix it
if it does.
I am only a minor technician who helped to coordinate
some of the technical aspects of getting the images from
the computers to the TV screen (working with people way
above my own understanding -- network specialists, physicists
from the U of Penn ....) but it did hurt a little (well, ok
more than a little...) to see comments making fun of
Terry Gross' appearance on TV, or hostile remarks about
Cliff Stoll (yes, he is a bit animated but a very nice
guy with a good bit of science under all that...) or
rude cracks about Bill Nye. I don't speak for the
station but only for myself -- and for myself, I am
saddened. Perhaps I am still to new to the Internet
and don't yet accept rude flames a "part of life" --
I do know that people say things that they might
not say quite the same way face to face..
All in all I think it went well for how complicated
all the elements were and the short time frame for
putting it all together. I am proud that so many
people outside of public television believed in this
project enough to devote time, energy and equipment
for it. Perhaps this gives us the vision of what
IS possible and the courage to try to refine it
even further.

The level of excitement that she & Levy had going were the high points
of the show. The net definitely has TV beat. I think the days of the
non-interactive medium are numbered. (Of course if I think of all the

to pull real internet into a live broadcast.

Elson,
Form the latest images the plume lasts approx. 10-12 mins. (our
time) then falls back down into the atmosphere after it cools off. This of
coarse is just fragment "A", the bigger pieces may cause a longer "HANG"
time.

At this afternoon's press conference (4PM EDT on NASA Select),
Shoemaker allowed as how he'd made a mistake in the conversion from
ergs to megatons. His current figures are 6 million megatons for
fragment G and 225,000 megatons for fragment A.

Here's another silly, pointless what-if question.
What if the Shoemakers and Levy had gone home early that night (as it
were), and had missed the comet? Is it certain that it would have been
noticed before Saturday by some other routine observation?
Or would we have been treated to the story of an amateur astronomer
suddenly calling some friends: "Hey, does anyone else see some weird black
spots in Jupiter's southern hemisphere?" Calls for emergency redeployment
of Hubble, attempts to get Galileo set up *real* fast, all that...

I'm very pleased with the attention CNN has given to the SL-9/Jupiter
event. Compare it with what all the other networks are (or aren't)
doing! CNN has a reporter on-site at STScI, they're covering part of
the press briefings live, and they're giving frequent updates.
I agree with "whitestone" that I personally find this event much
more interesting than O.J. Simpson's hearing, but we have to face
the fact that we hold a minority viewpoint. I think CNN is doing
a good job of balancing competing interests. If you want to see the
entire STScI briefings, ask your cable company to carry NASA Select.
CNN has consistently presented science events that other networks
have ignored. They broadcast every shuttle launch (even though it
was a split-screen with Simpson during the last one :-)) and have
done extensive live coverage of eclipses over the past several years.
No other network even comes close--not even PBS.
Sure, call CNN and let them know you'd love to see even more science
coverage--but keep the big picture in mind and realize that these folks
are acting like allies, not enemies.

I was _very_ annoyed this morning. In the run-up to the 0800 CET news
they said that the latest from SL/9 was upcoming, but then they cut to a
direct broadcast from North Korea of _videotape_(!) of Kim's funeral.
"Well, let's switch back and see what they're saying now." About as exciting
as watching grass grow. Shows the level of disdain they have for their
viewers! It was still going on at 0850 when I had to leave for work. :-(

Well, if they don't, they sure should've done something about it.
Though if I were living with the Great Red Spot in my backyard
I might have a different attitude towards a few thousand (or is it
million?) megatons of detonating ice overhead.
On the other hand, maybe they used mass drivers to break up some
of the small comet chunks last month :-)

Keith Schneider: sci.astro coverage on ABC 19 Jul 1994 09:46
Hmm... I was watching that very late "up to the minute" ABC news just
now, and they had on some guy talking about the Internet and its relation
to the comet collision, etc. Anyway, the guy said that he found some
pictures of the collision, and he had found out about them on sci.astro.
He showed the pictures as well as that animation...
Also, he showed two posts on the air. One was from some guy in Germany
who asked if the comet would ruin the Great Red Spot (or something),
and the other was a response to this, which basically said "No. No. No."
I should have looked more carefully to see the message titles... I tried
scanning the group to find such messages, but I didn't see them. All I
know is that the guy from Germany who posted the original message had part
of the Amiga logo in his .sig.
Oh well.. two of you now have national exposure (whether you liked it or
not). Hmm... I hope that nothing I write is broadcast outside of the

Ah. One of the Hubble photos on ftp.stsci.edu (HST_nuv_ACE) was taken
almost exactly 9:55 before one of my sketches. My spots 1,2 and 3 were
impact sites E, A and C. Site E, the youngest, was also the darkest;
site A, the oldest, was the lightest.
The Hubble photo shows no sign of the huge circular feature I saw
surrounding site C. I can't have dreamed this, my neighbour saw it
too. At 5:44 July 18, it was a thin dark circle centered on C and
reaching all the way to A. (Circularity assumed, the feature was
foreshortened by perspective.)
I heard no mention of it on the news. Surely someone else saw it?

Bill H B Jockey: White Sox play cruel prank on comet watchers 18 Jul 94 18:52
I've been following all the news about Comet Shoemaker-Levy 9 for over
a year now. Saturday night (fragment B) was our best shot at having
Jupiter in Chicago's sky during a collision, so I wanted to head over
to the Adler Planetarium and see what news we could get there.
Unfortunately, it was 95% cloudy out, and the Moon and Jupiter were
only occasionally peeking out, disappointing the crowds who wanted to
look through the telescopes. This didn't stop the TV news crews from
interviewing the astronomers live; the glare of their lights would
have been annoying if our sky weren't so overcast. Just about the
time that B was due to hit, I went inside and had a chat with one of
the Planetarium people about news coming in on the Internet...
When I stepped out the door again, I noticed a flash in the southwest
sky! This was the same compass direction as Jupiter and the Moon, so
it certainly got my attention!
Then I saw another flash, and a shower of colored sparks. Then red
ones, and green ones. Oh.
This was a bit much. I realized (1) I was watching a fireworks show;
(2) Comiskey Park lies south and west of the Adler Planetarium; (3)
the White Sox frequently stage fireworks after their night baseball
games are over.
I thought this was a rather cruel hoax for the White Sox to inflict on
the assembled crowd of astronomy buffs. It was a nice fireworks show.
But inside the planetarium they had some oral gossip, and were
displaying the two-micron images of the impact from Calar Alto, so I
was pleased. I felt I was getting at least a glimpse of the *real*
fireworks!

I've recently seen an article posted which gave approximate longitudes for
each of the impacts, including those which have already taken place... it seems
to me that there were a good number (perhaps 5?) which were to hit in the
range 320-330; 10 degrees on jupiter, though is quite a large space, but
there definitely is a chance we'll see "double" impacts, especially given the
"smearing" of the impact sites which seems to be occuring

Actually, now that you mention it, it seems very likely! If currents
don't throw off the propagation so the waves don't all hit in unison
after all.

This kind of thing is possible and being looked for -- not in sound
waves but in "gravity waves". Gravity waves are what expand circularly
away from the site where a rock is dropped into water. These are being
excited on Jupiter by the impacts and are being looked for by the
Galileo spacecraft and Hubble Telescope, if not by more. The waves
might show up as small, travelling fluctuations in temperature, which
could be observed as small fluctuations in infrared brightness.
As for wave focussing, one would have to assume that the travel time
to the antipode of the impact would be the same for all directions,
which is not likely given the density and temperature fluctuations caused
by the storms on Jupiter.

Sheesh! I'm afraid I have to agree...
Their selection of pictures was pretty terrible -- not even as good as
the local newscasts managed to find -- and they were not explained in
any coherent fashion.
I guess they wanted to do it "live", but I think it would have been better
to take some time to deal with some earlier images properly. (Hey! I just
remembered that they said they were going to show some HST shots, but we never
actually saw them, did we...?)
I was hoping for something that *hadn't* been covered -- and better --
in the news, but it was pretty much a basic primer for those who haven't
been following events. Uhh... *are* there any such people? If there are,
they probably weren't watching anyway.

(:-)) Yeah -- loved that bit, too.
>David Levy is getting good.
He had good screen presence. Better than the astronomer `host', anyhow.
>What is Cliff Stoll doing on the program?
His style was about as out of place as Nye's, but he *is* the only person
I've heard so far point out the distinction between the IR images (bright)
and the visible/UV ones (dark).
>And what in the Hell are they doing scrolling random email across the

Gawd that was bad! You couldn't read it *and* keep track of what was
being said. And I caught one URL scrolling past with no possibility of
identifying it. Well, it is on tape, at least.
> And why the distracting graphics in the background on the set?
Again, complete agreement.
I did rather enjoy seeing Clarke again -- even in freeze-frame!
PBS -- this is supposed to be *your* turf! If you can't do better than this,
you might as well pack up and go home.

I did watch it and it was a piece of crap.
Very few images, the 'net has definetely more
The presentation were quirky at best....

I did.
Who programed that mess? Sesame Street?
Dr. Science belonged on that idiot Beekmans World. Very Sad.
Images presented were not even close to what is on the net. I feel
sorry for those who do not have access as they are missing out on
quite a lot. This show did little for them.
In places it was good. I did enjoy the truck driver.
Overall. Thumbs down. Next time treat they should treat the subject
matter with a adult flair.
Oh, who was the idiot that decided it would be 'neat' to put
INET traffic on the screen. It was impossilbe to follow that and
the program at the same time.
I was dissapointed that they did not show the public the other
HST images that are availble. At least they could have shown
other HST images that are floating about the net since the
HST repair.
But NOOO>...some gooball had to put lame Mr. Science on. How many
6 year olds are up at 11:30 pm ?

Probably dark Jupiter glop exposed to view when high-reflectivity
ice crystal like material was evaporated by the heat of impact. Like
dark matter mixed with snow and then having the snow evaporate.
