Hi all, ... The interesting thing about C/2003 Q1 and C/2003 Q6 is that the latter can be brought a little bit closer to the Marsden group by excluding the...
Dear list members, There was just an article published about sungrazing comet in the "most important" (in terms of impact factor...) astronomical journal...
I see that an MPEC for the new one is already out: http://cfa-www.harvard.edu/mpec/K05/K05R06.html By this solution, it would seem not to be a Marsden at all,...
Maik, ... Of course, the orbital arc is short but in this case the data quality seems to be even more problematic since the rms is large for all orbits. For C2...
Hiho, ... yes, also rms residuals of smaller than 5 arcsecs have been seen, too. ;) There is a nice dependence of the residual value and the number of...
Thanks, Maik, I appreciate your looking into this. And thanks for your comments, Sebastian. I guess we may never know for sure what the true orbit of this...
Hello list, If the periodicity of the Kracht group is really around 5 years, we should expect the return of C/2000 O3 (SOHO) quite soon. This Kracht comet was...
You are correct Maik. This is not so easy. There is a great deal of research and studying that has to be done for one to understand comet orbits and orbital...
Hi Steve, ... Try FindOrb by Bill Gray http://www.projectpluto.com/find_orb.htm ... Yes. ... Yes. ... 'Comparing' is not really a good word for it. Of course...
Thanks Maik, This information you have given me will add to my "temporary" limited knowledge of the subject and maybe some day soon I will be able to perform...
Hi all, now available as a pre-print is a paper by Sebastian F. Hoenig (accepted for publication in Astronomy & Astrophysics) in which he sucessfully links...
Hello Jeremy, ... First, you copy a number of LASCO images into one single image (different levels). After that open "Windows --> Animations" in the top bar. A...
Jeremy, ... Which comet Machholz do you mean? There are 10 comets which bear this name and two others where this name is shared. Anyway, the name Machholz...
Nice comet Hua! It is really beginning to brighten up well. As bright as it is, one would think that it should begin to produce a tail. I guess if it is made...
Hello I analize archive SWAN images on 'SWAN Summary Images' http://sohowww.nascom.nasa.gov/data/summary/swan/swan-images.html and I found unknow comet. I use...
I search in archival MPEC data of comets to SkyMap (20010921.txt) on SkyMap web page and I load them to SkyMap. I found this comet, this is P/2001 Q2 (Petriew)...
Hello! I rechecked my downloaded c2 photos recently,and I found a really faint object two weeks ago.I didn't dare to report it for it was too faint.So I want...
I can confirm Hua's comet. picture size: 1024 * 1024 0,0 upper left 20050919_0042_c3.gif (620,648) It almost appears to have a small fracture/companion. 0018...
Dear Wentao, I have check this report and I can not see anything that I could confirm. Better luck next time! :) Regards, ~~Karl ... faint object two weeks...
Most of the Kreutz Group comets appear to travel the same path. Usually within a few x,y pixels of the previous comet, and this slowly changes throughout the...
Hi Steve, There are (approximately...) two sub-groups within the Kreutz group, imaginatively named sub-group I and sub-group II. (It does actually split up a...
I wonder that if I found a comet-liked object on the SWAM picture,how can I report?Is it the same as reporting a c2 or c3 comet? I hope someone could help...
