* Profile

Kazuo Kinoshita's calculation revealed that it approached to Jupiter down to 0.08 A.U. in 1988, and the perihelion distance was reduced from 5.2 A.U. down to 2.7 A.U.

It was discovered in 1992, when it passed the perihelion of the small distance for the first time, then it reached to 16 mag. But in the next return in 1999, it only reached to 18 mag. In the next return in 2007, it became fainter furthermore, and it has not been recovered yet.

The absolute magnitude of the comet has been fading, 7.5 mag in 1992, 8.5 mag in 1999, and fainter than 9.5 mag in 2007.

Kazuo Kinoshita's calculation revealed that it approached to Jupiter again in 2047, and the perihelion distance will be increased again, up to 3.6 A.U.
