Hi all, During the last five days I have worked with Karl Battams and Brian Marsden on astrometry problems with LASCO C2 images and as one result, a reasonable...
Hi all, Rainer lately told about the improved reduction method for cometary positions based on an largely increased number of reference stars. I can confirm...
Hi Maik and all, I'm glad the new C2 catalog is working out well. There were several reasons for the old C2 catalog being as small as it was (mainly related...
Hi Karl, ... thanks for this additional information. Usually I recalculate all Meyer group comets and often receive some differences to the MPC solution....
Hi Karl, if you talk about a wish list, I will wave my hand and throw in the apparitions of 1999 R1. Cheers, Sebastian ... -- ... Sebastian F. Hönig ...
Hi Sebastian, Yes, somehow I suspected you might say this... :) I'll see what I can do. (I'm still waiting for Maik's "wish list", consisting of every ...
Hi Karl, ... hehe. ;) Don't worry. I see no point in re-measuring the Meyer group comets since the orbit is statistically well defined (80+ comets). And to...
Hi friends, I'm giuseppe pappa, I see a point that for my It could be a comet,but it's visible in only two image because there aren't new image of SOHO. The...
... Hi, there are two additional positions 12:42 214 654 13:18 220 652 but it's not on the main track of the Kreutz comets but close enough to be an outlier ...
From the identification C/1996 X3 = C/2002 N2 the next perihelion was 2008 February 13 at about 00:25 UTC. C/1996 X3 and C/2002 N2 were observed only with...
... Nevertheless, it may be return of the comet C/1996 X3 = C/2002 N2. Pixel coordinates: (0,0) Upper Left. 20080213_1406_c2.gif 723,314 20080213_1430_c2.gif...
Dmitry, ... sorry, without even looking at the images - this is noise: The differential speeds in pixel/hr x: 57.5 -> 80 -> 75 y: 7.5 -> 5 -> 10 This is not...
Gidday All, I see a Faint Kreutz leaving the Stereo HI1a imager late 20080216. Should be detectable in mid 20080217 images? but I don't see it. Probably around...

Hi list, I think that Hua's Kracht comet is one of the fragments visible of September 2002. So, we should to see next one/two for few days... What do you...
... September 2002. ... I think that the Kracht group comets from September 2002 will return later (June/July) this year and that Hua's comet was not observed...
Hi all, is it really a Marsden group comet, Hua Su has just reported? I wonder whether it is a non-group comet... Cheers, Maik -- If they give you ruled paper,...
Yes, I agree. It just seems a little too bright, and to be moving a bit too fast, to be either of those. No sign of a tail, unfortunately -- that would seal...
Hi All, I posted this on the "stereohunter" group, but then decided it was relevant to this group too (so apologies to those who receive this twice). MPEC...
Can you guys confirm this please? Am i still seeing Hua's comet here in C2, moving lower and left, below the sun. 17 c2:20080306_1530_c2 808 818 87 99 18...
Hi Alan, Hua Su's non-group comet was easily visible for quite a while in C2 images today -- on both sides of the bright flare/spike coming from the sun in the...
Kracht group update I have measured the positions of the new Kracht group comet from 2008 March 03 with Astrometrica and found that this is the return of...
Hi list, it will be interesting to see whether Rainer's C2 claim is really a Meyer group comet as Bo has suggested. While the general direction may fit, this...
... Meyer group ... brightness ... fainter - and the ... I called it a non-group, because it doesn't fit the ordinary Meyer group comets. Later I realized that...
Rainer, and all, ... hmm, this would be a great discovery, if true. But I guess this could only be confirmed if further comets could be linked. To find out...
