Reports from Geisei Observatory <December 11, 2004>


• P/2004 V5 (LINEAR-Hill)
   Observation results of P/2004 V5, a comet with two nuclei.
    The image of the nucleus B is poor. It is also diffused and the accuracy of the measurements is a slightly inferior to that of the nucleus A. The nucleus A is 17.5 magnitude and the nucleus B is fainter at 17.9 magnitude. The two nuclei are about 2' apart and spanned by a white rainbow. The following are the observations by the 60cm telescope at Geisei:

• C/2004 Q2 (Machholz)
    This is a photograph of C/2004 Q2 (Machholz) taken by the 60cm telescope. A straight jet is observed running to the north. It has probably become visible today or quite recently. The tail extends to the north far beyond the 1.5-degree field of the photograph.
    I saw the comet with the naked eye very clearly today. It was slightly brighter than 5th magnitude. A color photograph of this comet will be presented later.


C/2004 Q2 (Machholz)
8-minute exposure from 23:52, December 10, 2004 J.S.T.
