Hi all, Today I retraced the latest four SWAN images from 2007/02/13 to 2007/02/18 for comet 2007 E2 discovered by Terry few days ago. I found something...
Hi All, With the latest three SWAN images now posted, 96P/Machholz 1 is easily visible. Approximate coordinates, measured from upper left corner are: 3/13...
Dear all, I have no access at the animation to see if this object is a know object, so I reported the positions in wait others images: 640x480 (0,0) upper left...
Hi all, Finally comet C/2007 E2 can be easily detected in the latest three SWAN images. Rough position: picture size: 640 * 480 (0,0) -- Upper Left picture...
Potential faint comet in SWAN images. (0,0) - upper left 13.03 262 224 14.03 260 224 15.03 258 224 This position is very close to P/2006 Y2 (Gibbs), but comet...
Hi Vladimir. I saw your object, for me is another interesting object. Don't seem on the path of the comet 39. We must wait other images. Regards, Toni...
Hi! I've seen your reports about possible comets in SWAN. I've not looked at these Pics, yet. Are that Aera's in a field with a change to search there from...
Gidday all, For those who are prepared to download STEREO images and use ImageJ , MAC or PC(windows/XP) software. Here is a very easy no fuss macro you can run...

20070328-meyer-bz-C2-collector.gif Recent Meyer comet in C2. rgds, Alan. In this recent plot of the Meyer comet I have noticed that it seems to have two...
Hi Alan, ... yes, Meyer group comets are almost always elongated this way in C2. I guess this is due to the fast apparent speed which leads to trailed images...
Oh, another one... ... you'll also notice that stars in the edges are elongated anyway, due to the optics characteristics. Maybe speed and optical effects...
... Probably speed is not the issue here. The C2 pixel scale is at best few arcseconds. If you now want the trail to be distributed over at least 3 pixel, you...
Thanks Gents, For the Help with my understanding of these images. So, the C2 resolution will not make any separation evident, unless it was very apparent like...
