Reports from Geisei Observatory <January 30, 2005>


• C/2003 K4 (LINEAR), C/2004 Q1 (Tucker), and C/2004 Q2 (Machholz)
    These comets have been recently observed. They are all visually observable with an aperture of 15cm or larger.
    C/2003 K4 (LINEAR) has moved up north.
    C/2004 Q2 (Machholz) is visible to the naked eye without much fading.
    There are only few measurements whose errors may exceed 1", but, because C/2004 Q2 has a large coma, the errors could be nearly +/- 2". Nine to eleven comparison stars were used. The average residual is 0.4".
