Abstract:
B, V observations of the eclipsing binary RS CVn have been presented. A dip around 0.ᴾ1 appears to be a wave minimum which fits well in the 'Wave minimum phase-time' relation, but deviates from the 'Wave aplitude-time' relation, derived for the RS CVn. Either, the 'Wave aplitude-time' requires a modification or the amplitude of the wave minmum appears masked by the intrinsic variability of one of the components or by the Sun-spot activity of the system. The colour exhibits variation. The secondary component appears active.
