P/1997 B1 (Kobayashi)
On January 30 and January 31, 1997, Takao Kobayashi observed an object, P/1997 B1 (Kobayashi), which was initially thought to be a minor planet and was reported to the IAU as such by S. Nakano. Over the next few days, the object was observed to be in a cometary orbit. W. Offutt later showed it to be a comet.[1] For discovery of a comet with CCD, as well as the faintest discovery, Kobayashi ranks the first among amateur astronomers. It demonstrates that amateur astronomers still have an important role to play in the field of astronomical object discovery.[2]
