Reports from Geisei Observatory <June 17, 2009>


C/2008 Q3 (Garradd) and P/2009 L2 (Yang-Gao)

    Is it a break in the rainy season? We haven't had much rain. The sun shines everyday and the mountains and fields are lush green. But, when it comes to observing, unusual clouds and haze build up at night making observation difficult.
    The following are the recent observations made during evening.
C/2008 Q3 Garradd is moving northward and can be visually observed, but good images could not be acquired due to unfavorable sky conditions. There are some uncertainties particularly about the observation made on June 17.
    New comet P/2009 L2 appears as a tiny point with an almost invisible fuzziness around it. You may wonder if it is really a comet. It is moving northeast at a relatively fast speed. I entered the MPEC's preliminary orbital elements determined by observations of a mere two days, but the telescope accurately tracked the fast-moving comet.
