A search for brightness pulsations of V1500 Cyg with periods of 1 millisec to 0.2 sec is discussed which was conducted in September and October 1975 with the aid of a television camera installed at the coude focus of a half-meter meniscus telescope. No pulsations having an amplitude of more than 0.2 magnitude were observed. A mean light curve is constructed on the basis of 2550 television pictures taken through a light filter centered on the continuum region near 555 nm over the period from July 23 to August 2, 1976. It is shown that the light curve had two maxima with different shapes, that the period of V1500 Cyg in July 1976 was 6 hr 28 min, and that the mean amplitude of brightness variations was 0.45 magnitude. These results are taken to suggest that V1500 Cyg is a close binary system.
