1 GCVS Team Porb = 0.137551d [A.P.Cowley, D.Crampton, J.B.Hutchings, J.M.Marlborough, ApJ 195, 413, 1975.]. Along with light variations typical for Z Cam variables there are sinusoidal variations with amplitude of about 0.2m B and variable period: P = 0.1329d (1961 - 62), P = 0.1327d (1966) [J.Smak, K.Stepien, AA 25, N4, 379, 1975.], P = 0.1326d (1978) [M.Sztajno, IBVS N1710, 1979.]. Sinusoidal variations are superimposed by quasiperiodic oscillations up to 0.2m with 8 - 20 minutes cycle and irregular flickering up to 0.1m in 1 minute.
