Abstract:
Photoelectric light curves of BH Vir in the UBVRI bands observed by
Arevalo et al. (1987IBVS.3117....1A 1987IBVS.3117....1A, 1990ApJ...354..352Z 1990ApJ...354..352Z) in 1986 were
analyzed by using the latest version of the Wilson-Devinney program
and to investigate the photometric parameters and spot activity.
Satisfactory fits were obtained by assuming a hot spot only on the
secondary star.
