Reports from Geisei Observatory <September 20, 2001>

• Observation data: C/2000 WM1(LINEAR), C/2001 Q4(NEAT),
P/2001 R1(LONEOS)
In summer time any objects fainter than the 18th magnitude is difficult due to film fogging. C/2001 Q4, which is predicted to be a great comet in four years, is still a microscopic existence on film. The coma is only 5" in diameter without any tail. P/2001 Q2 has become fainter by nearly a whole magnitude since its discovery, but I will continue to observe it by the 20cm refractor. C/2000 WM1, presented here today, is expected to brighten in January.
