AbstractWe study the circumstellar interaction around SN 1993J by its intermediate-band light curves obtained by the 60190 cm Schmidt telescope at Xinglong station. The optical emission showed a slow decay of 0.05 +/- 0.02mag/100 d in the period from 1995 to 2003, invoking a main energy contribution from SN-circumstellar interaction at late times. The relatively flat power law SN density model fits better with the observations. In particular, the line ratio of [O III]lambdalambda4959, 5007 and Na I D relative to H-alpha are well reproduced by the model. Moreover, the H-alpha light curve displayed obvious bump structures at some epochs, which is probably attributed to the density fluctuations in the ambient material that surrounds the reverse shockwave.
