Comet 17P/Holmes

While a group headed out to observe the comet from the alternate site, I observed it from my backyard last night with my 7×50 binos around midnight. It appeared to be a little larger than Mars and had distinct colour. I could easily see a yellow core surrounded by a soft green coma (even with the moon, street and house lights). I didn’t notice that the core was slightly offset from the center, but then binos didn’t provide enough magnification. No perceptable tail.

I’ll be looking forward to when I can train one of my scopes on it to bring out more detail at higher magnification. This “star” was very easily naked eye observable. Didn’t need any charts to figure out that the upside down stylized “F” of Perseus had a new visitor. It appeared to be the 2nd brightest object in Perseus. It’ll be interesting to observe it’s position change over the next few days and weeks (if it stays this bright).

Let’s see and hear the reports from the others that were out observing. I understand that some photos have been taken, and I know we’re eagerly waiting to see some of them. Hopefully the “Astro-Dollies” will post some of their antics and adventures from last night.

I have just come in from observing our new visitor, and Glenn’s description is quite accurate. Comet Holmes is easily recognizable as the star that doesn’t belong in Perseus! I believe Glenn’s estimate of mag. 2.5 is as good as any guess I could make. Through both my 10x60s and 15x70s the comet appears quite compact, tailless, and very bright. The halo is dense, and although to the naked eye the comet appears stellar (at least to these old eyes on a near full moon night) through the binos the halo has quite a bit of texture. I also found it to have a warm colour to it. Looking with my 5″ dob at 72x and then at 140x showed a remarkable sight. The core appears very bright, small but non-stellar, and embedded in a halo. It is not centered in the halo; I found it to be close, but slightly off center. Then there appears to be an even fainter halo surrounding the whole thing. So there seems to be three definable regions. The soft yellow colour seems present in the scope too. What does everyone else see? I am looking forward to further developments. It is changing daily, so keep your eyes on it!
