Abstract: We present photometry of the asynchronous polar Nova Cygni 1975 = V1500 Cyg in a 25 years after its outburst. This binary clearly shows light variations both at the orbital period, and at the spin-orbital beat period, 8.4 d, which indicates asynchronous motion of the binary components. The orbital R amplitudes are practically constant over the beat period. This could be caused by the variable accretion rate/brightness of a ring surrounding the white dwarf depending on the orientation of the white dwarf magnetic pole in respect to the red dwarf.
