C/1999 R1 = C/2003 R5***************************
Hi all,
congratulations to Sebastian!
He has made the first sucessful prediction of the
return of a SOHO comet.
Bo Zhou's C2 comet will have a perihelion time of
about 2007 Sep 11.07 only some hours before the
computed (C2+C3) time of Sep 11.26.
Regards,
Rainer

Oops, Bo Zhou's comet will be at perihelion
about Sep 11.3 (very close to Sebastian's prediction!).

Gidday All,
Well done Sebastian!
What is an estimate of the brightness of the comet in C2. I was
looking across HI1b, we still have the next sequences 0908 - 0910 to
come. Could it be detectable there?
Kind regards, Alan.

this comet so accurately! And congrats, Bo, on finding it.

I think I can safely speak for the whole SOHO team when I say "many,
many congratulations, Sebastian (and Bo)!!"
And as with all of SOHO's comet successes, you all deserve a share of
the credit for yet another tremendous achievement.
Best wishes,

Re: C/1999 R1 = C/2003 R5Hi everybody,
many thanks for all your congratulations, and in particular to Bo for finding
the comet. It's a pleasure to see that the comet is so close to prediction and
appears to be in good shape. Once I have the SOHO astrometry in hand, I will
also try to find the comet in our pre-perihelion ground-based data from Tahiti.
Though it was too faint to be directly recovered, I have some hopes that with
better known ephemeris and motion, it can be identified in the stacked images.
Cheers,
Sebastian

It seems to have 6-7mag in C2, as expected from the previous passages. You might
find the comet at 10-12 mag in HIa.

Sebastian

BREAKING NEWS: P/1999 R1 has been recovered!
Bo Zhou recovered the comet in C2 images of Sep 10, 2007. Although there is no precise astrometry available yet, it seems as if the comet is within 0.5 days of the predicted perihelion passage.The above animation is a crop of C2 images from Sep 10 21:09 UT to 23:54 UT. The comet moves from center-left to top-right and brightens significantly. The brightness should be ~6-7mag as expected.

C/1999 R1 = C/2003 R5 = 19?P****************************
Dear list,
with pleasure I congratulate Sebastian for his successful prediction of the
identity of SOHO comets C/1999 R1 and C/2003 R5. His identification and
linkage was published in Astronomy & Astrophysics and a summary can be
accessed at
http://www.mpifr-bonn.mpg.de/staff/shoenig/index-Dateien/Page434.htm . The
paper is also available as an arXiv preprint.
His original prediction for the perihelion passage in 2007 was Sep. 11.263
and the comet discovered yesterday by Bo Zhou seems to fit closely into this
prediction! What a fantastic achievement!
I know that Sebastian has searched ground-based from his remote observatory
on Tahiti prior to perihelion but found nothing. He also published a revised
brightness prediction. The current perihelion passage may therefore be used
to set some lower/upper bounds for its brightness behaviour. I guess
Sebastian will give some details of the pre-perihelion searches he
conducted.
Anyway, ONE SOHO-COMET LESS! The count has to be reduced by one.
Again, a great acchievement and if I'd be responsible for the naming of
comets I'd call it SOHO-H鰊ig from now on!
Cheers, Maik
-----------------------
Re: C/1999 R1 = C/2003 R5 = 19?P
Congrats to Sebastian,
I hope it does get renamed, Comet H鰊ig. There are precedents (eg
1P/Halley).

Re: C/1999 R1 = C/2003 R5 = 19?P
Terry and Maik,
many thanks for the congratulations. It was very nice to see the emails on the
recovery this morning. Actually, I wouldn't have thought it is that close to the
weighted C2+C3 orbit from which the prediction was made.
As Maik pointed out, we (i.e. Jean-Claude Pelle, Noeline Teamo and myself) tried
to pick up the comet pre-perihelion from Tahiti with our 14" (Hibiscus
Observatory) and 16" (Tiki Observatory) telescopes at solar elongations between
30 to 16. For that, I've had a look into the available SOHO photometry and made
an updated light curve with H=22.1 and n=5.1. At the time of our observations,
the comet should have been around 18-20mag. Unfortunately, we couldn't do any
better than 17.5 due to the bright sky background. Anyway, with the recovery, I
have some hopes that we may find it in the data.
Cheers,
Sebastian
---------------------------
Re: C/1999 R1 = C/2003 R5 = 19?P
Dear Sebastian, and everyone,
A very pleasant thing to read upon checking e-mail first thing in the
morning!
Very hearty congratulations to Sebastian for his successful prediction, and
also to Bo Zhou for his recovery!
I'll admit that I was in the "skeptical but hopeful" mode, but as the old
saying goes, the proof is in the pudding, and the evidence has really come
through. The fact that Sebastian's prediction seems to be no more than an
hour off or so is especially remarkable.
I completely concur with the earlier suggestions that the comet be named
P/SOHO-Honig (or something along those lines), and there is indeed precedent
for such an action.
Again, congratulations!
Sincerely,
Alan

Hi Sebastian and all.
Congratulation for this prediction. I was been skeptical about the return
of this comet, but I am happy to be belied:-))
This open a new phase regarding Kracth Group. There are other comets that
can to return in the next future.
I think that do you must to apply your work at other comets potentially
survieved at the perielion.

News （2007 September 11）
A non-Kreutz comet discovered on Sep. 10, 2007, in C2 images of the SOHO/LASCO coronagraph is most likely identical with comets C/1999 R1 and C/2003 R3 as predicted by Sebastian F. Hönig (Bonn, Germany). In 2005, Hönig linked the 1999 and 2003 comets and predicted the next perihelion to occur on Sep. 11.26, 2007. The comet found by Bo Zhou is expected to pass perihelion within a few hours of this prediction. If confirmed this comet will be the first safe periodic SOHO comet and the periodic comet with the smallest perihelion distance (0.054 AU). The comet will most likely be numbered in the near future and it has been suggested by several people that it should be renamed for Hönig. (Comets Mailing List, SOHO comet hunter Mailing List)-----------------------------
http://www.comethunter.de/
NEWS
10.09.2007 Bo Zhou found the returning comet C/1999 R1 = C/2003 R5 (both members of the second Kracht group, which had only three members) in LASCO C2 images of 2007 September 10 19:31 - 21:30 UTC moving very close to the prediction of Sebastian H nig. This proves that C/1999 R1 and C/2003 R5 are two apparitions of the same comet. The second Kracht group has now only two members and cannot longer be called a group. Sebastian has made the first sucessful prediction of the return of a SOHO comet.------------
http://www.rkracht.de/soho/
Highlights
1.The Kracht II group comet reported by Bo Zhou is the return of the comet predicted by Sebastian Hoenig, confirming the identity 1999 R1 = 2003 R5. The preliminary time of perihelion is September 11.1, compared to the prediction of September 11.3. Following the precedent of comets 1P, 2P and 27P I suggest that the comet should now be re-named comet Hoenig. It will probably be numbered 192.2.Strong kappa Cygnid meteor activity was reported between August 10 and 19. The nature of the fireballs suggests a relatively recent cometary origin.
3.Rob McNaught has presented a framed montage of comet 2006 P1 to the BAA.
4.Newly discovered comet 2007 Q3 is currently over 7 AU from the Sun and not due to reach perihelion until 2009 October, when it may reach 10th magnitude.
5.The latest orbit for comet 2006 S3 (LONEOS) gives a negative value for the "original" 1/a, although the error bars include positive values. If further observations confirm the negative value, the comet could have originated from outside the solar system.

that sounds good. Can someone measure the C3 positions until Sunday and
provide it to Karl? It would be nice a) to have an official announcement of
the comet next week and b), more importantly, an improved orbit to re-check
the pre-perihelion ground-based search images. I guess the C3 images are not
yet available compeletely.
However, I won't be able to do this due to work-load issues.
