I refrain from withdrawing...


The following images showed again a cometlike object right on track.
Its unlike anything I have seen in the last 3 years, strange
behaviour, still possibly noise... The following images should be
decisive (I hope).

Okay, I leave the decision to Doug. The shape is changing but the

movement is consistent. I guess this behaviour is the result of the
image processing.

Here is a summary:

Hi All,


Initially I didn't find anything compelling in Maik's reported
C3 positions. However, beginning at 2002/2/4 15:42 I see an
unambiguous comet on a Kreutz trajectory in 8 consecutive
frames:

1024 x 1024 positions (0,0 in upper left):

15:42 122, 781
16:18 126, 777 +4, -4
16:42 130, 774 +4, -3
17:42 138, 767 +8, -7
18:18 143, 763 +5, -4
18:42 146, 760 +3, -3
19:42 154, 753 +8, -7
20:18 159, 749 +5, -4

My 15:42 and 16:42 positions correlate with those of the
object Maik was reporting, and his positions back to 11:42
extrapolate well from the above sequence. So somehow he
is seeing this object earlier than I am in the blue frames.
Congrats on this find! --Rob

Hi again,


Maik's C3 comet is now showing a nice little tail at 23:56,
position roughly 190, 722. --Rob

Some bad news,


"SOHO has experienced a thermal reconfiguration, warm startup
and an ESR, in an as yet unknown order. All instruments were
powered off at the LCL level. Cause for the above is not
known at this time. We are only getting low rate telemetry at this time.

The FOT is manually turning on heaters on the redundant side
for all instruments. The duty cycles may need to be adjusted
down later."

I don't know what the current status and outlook are. Acronyms
defined as:
ESR - Emergency Sun Reacquisition (safe-mode)
FOT - Flight Operations Team
LCL - Hmmm. That one's got me.

Also, I can confirm Maik's latest claim. It looks like it could
be a nice one. Too bad about the ESR. Hey, it feels good to
have our first comet of 2002!

Bad news, but not too bad. Recovery from this ESR and warm reboot
is expected to take several days. We don't expect to open the
LASCO doors until this weekend. Sorry, Maik, it would have been
a nice comet.

Latest update:

The LASCO instruments have been powered on and one image through
each of EIT, C1, C2, and C3 has been taken. They look good. The
LASCO doors are now being closed in preparation for further
spacecraft activities. Not sure when they'll be opened.

Check the images at:
http://lasco-www.nrl.navy.mil/realtime.html

EIT will be running at a 7 minute cadence while the LASCO doors
are closed. At least you'll be able to watch the Sun.

Hope for a big flare now that the HESSI mission is up. Though I
don't know when they'll be obtaining science data.

Roberto,


at the time the comet was observed there was already a report by
Mike Boschat suspecting a fragment. It turned out to be no real
object. Maybe you refer to the same? See:

(Apr 26 2001 19:56:56 20010426_2330.gif 512 x 512 109, 478)

but it not the same, at this time I can see nobody and there are
6 positions (perhaps only 4 real), the possible fragment
can to be see only on enlarged images.

Hi Roberto and Maik,


thanks to having an archive of all comets in 2001 I was able to
look at the original gif's. My result: No fragment.
The reason is that it is quite bright in the 00:06 and 00:54
frames but absolutely nothing visible in 23:54 and 00:30. One also
has to be careful because at this time C2 was covered with quite
much noise (not that much like after an X flare but anyway).

If one is interested in a short animation please contact me.

This sounds like a non-Kreutz. Mike O, you've checked this month

in 2000, remember something like this? Maybe it's an additional
member of "my group". The motions seems compatible with the elements
of the group (although they may be slightly out of the C2's FOV)
given that the FITS are aligned N-S (since the original FITS are
reversed). Remember, I've set a bounty for the finding of another
member! ;)
Please, can somebody recheck this before Doug will be
in the office on Monday?

I have tried to calculate an orbit for this comet. All I can say

is: The possibility of belonging to the group of 1997 L2, 2001 E1
and X8 is there, although other solutions coverged far better.
The last word will be from Brian Marsden.

Just to inform you that a re-evaluation of the positions of

Rainer's non-Kreutz of April 1997 gives orbital elements which
are closely resembling the values of the triplet. Seems like
number four (i.e. it should become a quartet) and that I owe
Rainer something. Thanks to him!

Tom,


this is no place for reorting comet discoveries made by your own
telescope. This is for reporting SOHO comets only (you should have
read the pages before posting!).

Besides that, such a bright comet would already be known and the
movement is quite fast which let's me suspect that it might be a
high cloud or something else.

Nevertheless, for comet reporting go to
http://cfa-www.harvard.edu/iau/CometDiscovery.html
this is the right place for your claim.

There is an interesting feature on the C2 sequence from February

14 between 04:30 and 07:54, where a dark feature appears to
approach the sun from about 3 solar radii to 2 solar radii (ie the
occulting disc) at roughly the 10 o'clock position. This appears
to show smooth motion, is diffuse and has a tail (also see the
difference images). I don't see how a dark feature can be a
comet, unless it is very gassy and happens to be absorbing in
the C2 wavelength. Jon.

Jon:


I just looped the images and it is either a
contrast effect OR one of those objects mentioned
in Sky and Telescope that are material falling back into the
solar surface, they had an image of one and it appears
dark and fuzzy.

First, the Feb 14th infalling event pointed out by Jonathon is almost
certainly of solar origin. This is something we see occasionally
in LASCO. Theories abound about the causes.

Second, I've confirmed the two archive claims of Sebastian Hoenig
on 20 Apr 1998. I found the first object in the Orange 512x512
image, but not the others.

Third, I'm still having a good hard look at the non-Kreutz archive
claims of Rainer Kracht.

In addition to Ceres, Uranus has been visible for the last

several weeks in both cameras (though it may now be too
close to the sun for it to appear in C3). However, Uranus
moves so slowly relative to the stars that no one would
confuse it for a comet... --Rob

I can confirm Rainer's second non-Kreutz claim of Feb 11 2002 

12:35:41. I have found the comet in C3, too. The comet swings
around the sun in a similar way to 96P/Machholz one month ago.

"I am surprise that nobody has found it."

Personally: I'm not staying up all night
to look anymore. I don't have the capibality
of downloading 1024 images. As I don't have
high speed internet. I have other problems
right now.
Also, can we put 2 posts per person
only? ie: 1 post for a possible find with coordinates
or 2 posts with a possible find then the next post
with coordinates. One does not need to post 2-3
times with coordinates. It's hard scrolling
through the posts to see what is going
one -- my opinion only...

Congrats on your find.

Due to various computer problems, we've been slow to deal with
many of the recent claims. I'm working to get much of this
resolved, but as I've been working on my other passion (solar
physics), there hasn't been much time.

Hopefully, you'll all hear more out of us soon.

P.S. Congratulations to Germany for both the most gold medals and
the most total number of medals in the Olympics. And
congratulations to Canada for winning both ice-hockey gold medals.

Hi all,
Many of you no doubt are aware that MPEC's are now out for
a bunch of the old reports we had not acted on. In addition to
those, I've had a look at the data for all of the reports up to
the current time. I'm listing below the comet numbers of all
accepted claims. There's only one report which has been denied
which hasn't already been withdrawn. That is the report by
C. Wright who has reported what somewhat obviouly just an
assortment of cosmic rays from Feb 25. Inspection of the images
shows considerable variation of the shape of the object, just
as expected for cosmic rays.

The current number of comets stands at 401. Woo Hoo!
That's 400 for LASCO and 1 for SWAN. Congratulations to all of
you out there who have contributed to this fantastic number.
We haven't made a big deal out of the '100' marks since 200. But,
it's time to start thinking about 500. Sometime this year, I will
run a contest for a prediction of the perihelion time of comet
number 500. Rules to be determined. Start working on your
prediction algorithms. Prize? To be determined. (I think I still
owe someone a free lunch for SOHO-200.) I paid off for SOHO-100.

I can confirm that R. Kracht's claim for an object on June 30, 1999

is valid. It moves right to left all the way across C2. I found
it on the East limb as well. I checked C3 and didn't find it,
but I suspect it might be there. Here're my positions:
(0,0) bottom-left corner, as always.
