I observed C/2000 A1(Montani) for the first time this year. As it was very far and faint, I was able to detect in its image only its coma less than 10' across. Although the skies over Geisei have become brighter compared to the time when Halley's Comet was observed (at 20.5 magnitude), the main telescope at Geisei Observatory is still very active. The above data will be simultaneously reported to the Smithsonian by the Internet. You are the first to read these data.
