Reports from Geisei Observatory <May 5, 2006>

73P/Schwassmann-Wachmann 3 and P/2005 XA54 (LONEOS-Hill)

    The following are the observations of Nuclei B and C of 73P/Schwassmann-Wachman 3. A photograph is also provided.
    In this color photograph the coma is large and the tail looks the longest so far. In a short-exposure photograph Nucleus C is larger than when it broke up. The magnitude given is the magnitude of the nucleus, while the total magnitude is 8. Nucleus AQ, which had split from Nucleus B, seems to have faded and become smaller.

    This is the last observation at Geisei of P/2005 XA54, which has become fainter. I am not quite sure if this comet can be captured on film at the next observation on a dark night.
