The comet was discovered at 17th magnitude on a schmidt plate by Claes Ingvar Lagerkvist. Calculations by Kazuo Kinoshita reveal that it passed extremely close to Jupiter in 1987 (0.0057 A.U.) which dramatically reduced the perihelion distance from 5.5 A.U. down to 2.6 A.U. When it came to close to the sun for the first time in 1996, it brightened temporarily up to magnitude 16.5 in an unusual outburst, when it was discovered. However, it quickly returned to the original extremely faint state, fainter than magnitude 20. Date 10x10 mag Error Kphot mag Coma '
