B, V observations of the eclipsing binary RS CVn have been presented. A dip around 0p.1 appears to be a wave minimum which fits well in the 'wave minimum phase-time' relation, but deviates from the 'wave amplitude-time' relation, derived for RS CVn. Either, the 'wave amplitude-time' relation requires a modification or the amplitude of the wave minimum 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.
