In this work, B and V photometry of the RS CVn-type binary II Peg is
presented. The light curves obtained in 1983 and 1984 display two
unequal maxima. The light curves of the system have different
amplitudes. The amplitude seems to vary with three different periods.
10, 6 and 4 years of periods may be attributed to those variations.
