Scientific paper

The photographic observations of the eclipsing variable SS Lac conducted by Mossakovskaya in 1989 failed to show eclipses at the time predicted from the ephemerides of Dugan and Wright (1935). From a composite photographic light curve of SS Lac constructed on the basis of literature data and observations based on plates from the Sternberg Institute in Moscow, it is suggested that the eclipses in SS Lac disappeared as early as the period between 1935 and 1940, and not during 1949-1950, as argued by Zakirov and Azimov (1990). The depth of the SS Lac maxima changed from 0.6 m pg in 1898 to 0.4 m pg in 1935.
