Observations of Comet 17P/Holmes in outburst.

Comet 17P/Holmes increased in brightness over a half of million times on 2007 October 24 ( APOD 2007 October 26 ). On November 1 it was still in peak of its brightness, when I pointed at it the 25-cm telescope of my home observatory located in the Nizhnyj Arkhys, Community of the Special Astrophysical Observatory in Karachai-Cherkesia, Russia.

Figure 1. Comet 17P/Holmes identified in the frame of SAO 1-m Zeiss all-sky TV camera on 2007 November 1.
