We report preliminary results of the UBVRI photoelectric and R CCD observations obtained in the Crimean astrophysical observatory and the Astronomical observatory of the Athens University. The light curve represents well-pronounced eclipses with a total duration of the most sharp phase of 0.d022. At the eclipse, the color index U-B becomes smaller by 0.m2 than outside eclipse, contrary to other colors, where the color indices become larger. This indicates a presence of uneclipsed source of ultraviolet emission, possibly the wind from the accretion disc.
