Here is a picture of Comet Holmes showing a very faint ion tail. Taken at 01:11 UT on 31 Oct 2007. http://www.astropix.com/HTML/SHOW_DIG/064.HTM Has anyone...
Great capture of the ion tail, Jerry! I suspect it visually as a brighter patch of the outer halo. After a couple days off from observing the comet, I was...
Here is another image of the tail of Comet Holmes taken last night (10/31/2007) with my AP160 at f/5.9 from New Mexico Skies. This image is a single 20 minute...
The pictures of Comet Holmes are starting to look more interesting, and more like a comet. I suspected seeing that tail Tuesday night with my 25" but oddly I...
... In short yes. If you look at your image it shows the tail faning to well above west. I did this sketch on the evening of Oct 30 when observing with an f/5...
Very nice image Jerry. In an image I took at almost the same time, false color gradient mapping shows the offset central brightness of the comet runs along the...
... I agree about the misleading, but as it is, the core is actually slightly offset as far as I can tell. In Photoshop, when I make a circular selection from...
This image shows what I mean: http://mikkel.messier45.com/gallery/test2/CombineFilesWgtMed.jpg The circle is exactly centered on the core. -- Best regards, /...
15480 Empire Rd. Benson, AZ 85602 hm ph: 520-586-2244 I looked at it with my 13-inch with no moon and in the hole between scattered high, thin clouds last...
Hi Kent, At about the 7pm orientation in my image there appears to be a possible anti-tail. I don't know enough about comets to be sure about that but there is...
That sounds about right, but I'm not sure if it was the tail or an anti-tail. My notes that night say that very same thing! Kent Blackwell ... possible ... but...
After a nice walk home from work, I was good and dark adapted, so I got the 100mm f/6 refractor back out again. The comet was still quite an easy naked-eye...

Using the picture on the link below I'm trying to estimate the diameter of the nucleus and can't get this to scale correctly, without making the comet...
Put the prefix "pseudo" in front of nucleus, then you've got it. We are not seeing the actual nucleus. We never do with our backyard scopes. After suffering...
Hi! I'm sorry this is not a visual report. I hope I'm forgiven. I was just so positively surprised by the details in the coma that I managed to extract from...
Mikkel, Your unmodified image captured clearly what I saw last night, Nov. 2, in an 80mm refractor, an 11-inch cat and a 15-inch Newt from Visalia, Calif. The...
I got a chance to view Holmes last night (before we were clouded out by the hurricane moving up the East Coast) in an NP101 and again found, as with the Star...
Hi Greg, At Okt. 28, I could see the nucleus with my 4" Newton (110x) as a very faint stellar point, much fainter than the 9,2 mag HD 23676 near the nucleus. ...
May I suggest some clafication in the nomenclare used to describe features in regard to P/Holmes. As time passes, I see the descriptions of the structures...
The pseudonucleus has also sometimes been referred to as the "nuclear condensation". I recall being introduced to that term prior to participating in the...

The pseudo-nucleus has faded during the last couple of nights. I was able to see the pseudo-nucleus from within the city of Vasteras (population 130 000) with...
Today the comets nucleus (pseudocore) was not visible at all in the binocolars, while it was easly visible only two days ago. Through larger telescopes the...
Howdy all; After observing Holmes last night we got to wondering just how large the coma of this comet is, considering it is beyond the orbit of Mars. Does ...
Hmmmmm...one source I saw indicated that it is now 70% the size of the sun. Neal ... From: Steve Coe To: amastro@yahoogroups.com Sent: Sunday, November 04,...
Hi Steve, here's my rough estimate. According to the ESA website ( http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=41491 ), the comet is 1.62 AU...
Hi! I just came in from having a quick look at the comet, and it's still beautiful :) Like earlier, it is now very difficult to see the pseudonucleus, in fact...
A friend and I were out last night using the FS128 under fairly adverse conditions (winds up to 30 mph, maybe more) so he didn't set up his 15" dob, but the...
Hi Steve ! Here are my calculations. The comet was at 1,6207 AU from Earth last night (1 AU = 149,598,000 km) and the diameter of the Coma was about 12 min...
