Comet 17P/Holmes

From: 2007-11-13 19:15 UT
To: 2007-11-13 19:38 UT

Comet Holmes was still visible to the naked eye although, right away, I could see that it was more "fuzzy" and not quite so bright as the last time I observed it. It was also obvious that it had moved a fair bit since the last time I'd observed it. It was now fairly close to Mirfak.

It also looked a little different in the binocular too. While it was still circular looking, with no hint of a tail, it now appeared to have a bright "spot" in the middle of the circle and the brightness of the circle dropped off as you looked further out to the edge (the difference here being that the last time I observed it the edge of the circle appears to be quite bright compared to the rest).

I did notice that part of the edge still also less bright than the rest of the edge.

By 19:38 UT cloud had taken over so I packed up and headed back indoors.
