摘　　要：This paper briefly describes the small scale splitting of the nucleus of comet Hale Bopp which was observed on March 4,1997 by use of the 200 mm refractor at Purple Mountain Observatory.It is also shown that the separated small fragment of the nucleus has its own jet with a projective length of 5.04×10 3 km,while the maximum projective distance between the two separated nuclei is about 2.19×10 4 km. The data were processed by use of image enhancement technique.This paper briefly describes the small scale splitting of the nucleus of comet Hale Bopp which was observed on March 4,1997 by use of the 200 mm refractor at Purple Mountain Observatory.It is also shown that the separated small fragment of the nucleus has its own jet with a projective length of 5.04×10 3 km,while the maximum projective distance between the two separated nuclei is about 2.19×10 4 km.
