Resumen:
In this work, we studied the Mount Wilson indexes we obtained indirectlyfrom both IUE high and low-resolution spectra of the RS CVn-type systemsII Peg (K2IV) and V711 Tau (K1IV+G5V). For both systems, wefound a long-term chromospheric activity cycle related to the meanlevel of activity of the primary star and a shorter cycle associatedto the non-axisymetric redistribution of active regions on its surface.
