The TV-photometrical investigation of V1500 Cyg were carried out in 1982 - 1986 at the 0.5-m telescope of the Crimean Observatory. The mean brightness of the star decreased to 16.5 - 17.5m(V). It is detected that the period of 0.139d variability increased by 2×10-6days as compared with the period observed in 1978. The color indexes B-V and V-R are found to be dependent on the phase of the period.
