Reports from Geisei Observatory <July 18, 2007>


C/2006 VZ13 (LINEAR) and 17P/Holmes

    The following is an observation of C/2006 VZ13 (LINEAR), which is brightly glowing in the evening skies. As you may have seen in the photograph in the Diary entry of July 15, the comet is a binocular object and moving south rapidly. By a visual observation in the 20cm refractor at 60x the extensive, diffuse coma in a 6-7 minute diameter stood out, but the tail could not be confirmed. The central brightening was clear and the comet will be visible in the evening sky for a while.

    17P/Holmes is brightening in the pre-dawn skies.
