摘要
The CCD photometric observation of secular periodic comet C/1995 O1 (Hale-Bopp) was carried out at the Sheshan Station of Shanghai Observatory of China. We obtained 23 CCD images on 1996 March 11, April 22 and May 22. We derived the magnitude of the cometary nucleus in V, R bands, and estimated the lower limits of cometary mass and size. The results show that the diameter of nucleus ≈ 5 ～ 10km, which corresponds to a mass of 2 × 10 12～ 3 × 10 13 kg for different parameters when the bulk density is assumed to 1000 kg·m -3.
