* Profile

New periodic comet discovered in 1999. But in the next return in 2008, it became fainter by 2 mag.

Kazuo Kinoshita's calculation revealed that the perihelion distance has been almost constant at 3.6 - 3.7 A.U. since 1952. Therefore, the brightness of the comet should be also stable.

In the apparition in 1999, the comet was not observed in 2000, one year after the discovery, although it must have been almost as bright as at the discovery. It suggests that the comet was temporarily bright in outburst in 1999.
