Photoelectric photometry of the unusual binary system, whose light curve shows peculiar light variations, has been done in the two colours. The observations obtained at the Ege University Observatory between 1973 and 1978 and at the Kottamia Observatory in November 1977 show a variable light curve. The observed variations in the light curve show a migrating wave towards a decreasing orbital phase similar to those observed in RS CVn-binaries. The migration period appears to be about 191 days. The times of minima indicate that there has been a decrease on the orbital period of the system. However, since there is not enough material on the observed times of minima, we cannot explain whether the decrease in the orbital period has been sudden or gradual. The radii of the components have been computed from the primary minimum alone. With the available spectroscopic data, the absolute dimensions of the components are also presented. It appears to be difficult to explain the evolution of the system without taking into consideration the mass loss. The proposed models for the evolution of the system and an explanation of the observed light variations are also presented
