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.
