Reports from Geisei Observatory <September 23, 2018>


A photographic image of brightening 21P/Giacobini-Zinner

     On the morning of September 23, I photographed 21P/Giaconibin-Zinner during a brief moments of clear skies. It was at the 8th magnitude displaying a beautiful tail, though short. Many comet searchers must have come across this comet and be very impressed. September 19, 1965 was the day I discovered Comet Ikeya-Seki and it was positioned in a much lower eastern sky. At that time, Typhoon No.24 was approaching Japan, just like this year. Comet Giacobini-Zinner was visually discovered and will please our eyes for a while.
