Reports from Geisei Observatory <March 25, 2006>


C/2006 F1(Kowalski), C/2006 A1(Pojmanski), and 73P/Schwassmann-Wachmann 3 (C)

    The following are the results of the latest observations at Geisei Observatory:
    C/2006 A1 is at 8th magnitude and clearly visible in an 8cm finderscope. The tail is quite faint.
    Nucleus C of Schwassmann-Wachmann 3 has brightened significantly and looks great in the 20cm telescope. It is faint but detectable in the 8cm finderscope. Nuclei B and G will be observed later.

    Spring has brought more cloudy days resulting in a fewer observations. Yellowish dust from sand storms does not help, which has drifted over from the Asian continent.
