Reports from Geisei Observatory <July 28, 2012>

Comet P/2012 NJ (La Sagra)

    This comet with a stellar appearance was first discovered as a minor planet, but later it was identified as a comet when it was found to have a tail. It was likely a comet at first, but over a long period of time its coma had been ripped off.
    This photograph was taken with the 70cm f/7 reflector at Geisei Observatory. It is a point-like image without a coma or tail. It is moving rather rapidly through Pegasus to northwest.
