Abstract:
We present the analysis of new BVR light curves for the active star
SV Cam. The Roche model with spotted areas on the hotter primary
component fits satisfactorily all filter observations yielding two
spots in intermediate latitudes and covering about 1.5% each of the
stellar surface. Both are ∼1000K cooler than surrounding photosphere.
The comparison with an earlier season (January/February 2000) suggests
that the spots probably evolved in area longitude and latitude but
basic and preferred orientation from previous season is confirmed.
The comparison stars were SAO 1045 (standard) and SAO 1030 (check).
