I don&#8217;t have a great western horizon in this part of town. The comet had finally moved far enough south to give me a few precious moments with it before it slipped behind the trees and roofs. I found it first with my 15 x 70 binoculars from the back yard. I had to hustle to find a place where the 8-inch Dob could still see it from its lower point of view. (The sidewalk by the street worked.) The comet had a nice aqua color that was most noticeable at low power. It formed an obtuse right triangle with two other nearby stars. The core was concentrated, but the low-altitude seeing would not permit me to tell if it was stellar or not. The background of the view was filled with blue-gray twilight.<\/p>\n<p>There was barely enough time to make a crude sketch before it sank out of view. I was not able to spend time estimating the visible dimensions of the coma unfortunately. I did take a few minutes to re-draw it indoors so it was a bit more presentable. This poor comet is really dropping off everyone&#8217;s radar with 17P Holmes going nuts. Hopefully I&#8217;ll get a couple more days to track it before it leaves us for the southern hemisphere.<\/p>\n<table color=\"ffffff\" width=\"470\" border=\"0\" cellspacing=\"2\" cellpadding=\"4\" style=\"line-height: 150%\">\n<tbody>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Subject<\/b><\/td>\n<td bgcolor=\"#3f4d6d\"><b style=\"color: white\">C\/2007 F1 (LONEOS)<\/b><\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Classification<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">Comet<\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Position*<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">Virgo: [RA: 15:07:37.6 \/ Dec: +00:09:41]<\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Size<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">Not estimated<\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Brightness*<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">~ 6 vMag<\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Date\/Time<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">October 26, 2007, 6:45 PM<br \/>\n(October 27, 2007, 01:45 UT)<\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Observing Loc.<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">Flagstaff, AZ &#8211;
