Reports from Geisei Observatory <December 3, 2001>

• Observation data: 31P/Schwassmann-Wachmann 2, 19P/Borrelly, P/2001 Q6(NEAT), C/2001 U6(LINEAR), C/2000 WM1(LINEAR)
Because the moonlight was bright, instead of observation I made positional measurements on the film exposed in November. 31P Schwassmann-Wachmann 2 is at magnitude 11 with a tail and seems visible in 20cm-aperture telescopes. 19 Borrelly is a periodic comet. Although it is very faint, it is recognizable as a comet. C/2001 U6 was barely captured on film with a nearly 30-minute exposure by the 60cm telescope. It is slowly brightening. Observation will resume in the western sky around Tuesday. C/2000 WM1 will be photographed in color.
