Reports from Geisei Observatory <January 25, 2006>

Praesepe, Saturn, and P/2005 R2 (Van Ness)

    Cold but clear nights continue over the observatory. Saturn was shining side by side with Praesepe, as if it were ready to move into Praesepe. Taking advantage of the dark sky, I looked for the gegenschein. The glow of gengenschein is so faint that it becomes invisible when a planet is shining nearby.

    As for P/2005 R2, this will be the final observation of this comet, as it is low on the western horizon. I cannot go to the observatory often for early evening observations.

    The comet is diffuse and it is difficult to determine the center. The nucleus seems to be quite faint.
