摘要：

A CCD imaging observation of Periodic Comet Shoemaker-Levy 9 (1993e) was carried out at the Okayama Astrophysical Observatory. We derived the magnitude of ten large nuclei in the R-band, and estimated the lower limits of their sizes. The diameter of the nuclei is larger than 0.7-0.9 km, which corresponds to a mass of 2-4 x 10(11) kg when the bulk density is assumed to be approximately 1 g cm-3.
