New BV Light curves and Photometric Solutions for the Contact Binary Ss-Arietis

New complete light curves in B and V bands for SS Arietis are presented in this paper. As compared with the light curves obtained in 1982 by Kaluzny & Pojmanski (1984), the new ones show a marked change. The depth of secondary eclipse has increased by 0.047 mag. in B and 0.02 mag. in V, and the Max II brightness has increased by 0.045 mag. in V and 0.041 mag. in B. Using the 1992 version of the Wilson-Devinney program, we have computed photometric solutions from the new light curves of SS Ari. The present observations reveal that the asymmetric appearance of the light curves observed in 1982 is due to contribution from cool spots on the more-massive component of SS Ari, and that these cool spots completely disappeared in 1991.
