Reports from Geisei Observatory <December 6, 2001>

• Photograph of C/2000 WM1 (LINEAR) visible for only a few more days
LINEAR (C/2000 WM1) is moving fast to the south. By visual estimate (by the Pogson step method) at 18.30 tonight (December 6), it was at magnitude 6.2, 0.4 magnitude fainter than the nearby star SAO 147464 (magnitude 5.8T). However, on the negative film it looks considerably brighter than this comparison star. As light tended to be scattered at 60x, I could have slightly underestimated its magnitude. The photograph below was taken by a double exposure for one minute, 7 minutes apart. Its rapid movement is obvious against the background stars. It will be visible for only several more days.
