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