Photoelectric photometry of the V 1500 Cyg

Results of photoelectric observations of V 1500 Cyg made in the UBV system and in a special five colour narrow-band system are presented. The observations cover the decreasing branch of the light curve of the Nova between 30.8.1975 and 2.7.1976. The accuracy of the measurements is discussed. The short-period fluctuations with the main period of about 0.14 days have been detected on the light curve. Comparison of the results of the photoelectric observations with the results of different authors has revealed that fluctuations with the period of 0.141 day and the amplitude of 0.15 star magnitude have existed. It is shown that the amplitude of fluctuations decreases gradually and the period increases
