Scientific paper

Photometric observations of the WUMa system AEPhe obtained at La Silla in the years 1975-1977 are presented. The UBV light curves display marked variations with time. The two periods, 55d and 95d, found by Walter (1982) from observations in 1978, and interpreted as the precessional periods of the components, could be confirmed and refined to 55d.9 and 99d.6 It is shown that the variations of the light curve are caused by bright as well as by dark areas. Large light curve distortions were found in 1976.
