1 GCVS Team Min II 8.19; Min II - Min I = 0.506P; d = 0.033P. P var. Nonlinear term: -1.00d*10**(-8)*E**2. Wave-like distorsion with the amplitude from 0.09m up to 0.20m and with the period 4.7917d close to the orbital one is observed on the light curve out of eclipses [S.Catalano, M.Rodono, PASP 86, 390, 1974.]. The wave is migrating on phase in the direction of phase decreasing with a migration period of 9.48 years [J.A.Eaton, D.S.Hall, G.W.Henry, IBVS N1862, 1980.].
