Reports from Geisei Observatory <November 16, 2013>

Sudden brightening of Comet ISON

    I was startled when I looked through the 15cm refractor (x21) mounted on the 70cm reflector. The coma of the comet ISON was shining brightly as ever and the tail stretched almost beyond the 2-degree field of view. It was at 5th magnitude and a number of streaks were seen.
    Will it grow to become a great comet passing through the corona intact or will it disappear bathed in a million-degree heat? I hope this photograph will not become the last of Comet ISON. The excitement I had chasing Comet Ikeya-Seki on October 21, 1965, has returned!
