摘　　要：The light curve and images of comet Hale-Bopp(C/1995 O1) in Sept. 1996 are studied. It is found that an outburst happened in Sept. 10-11, 1996. The magnitude of the inner coma region increased by 2.1 mag. and 1.4 mag. on these two days, respectively. Two globular ejecta were found near the nucleus of the comet in Sept.10 and 11, 1996. By extropolating backward from the ejecta, it is found that the initial time of the outburst was on Sept. 9, 1996 (9.5±0.2UT). The physical reason for this outburst is still uncertain. The projected radial velocities of ejecta are 120m/s and 97m/s.The light curve and images of comet Hale-Bopp(C/1995 O1) in Sept. 1996 are studied.
