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!
