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.
