1 GCVS Team B - V: +0.09, +0.39. P var. Before JD2426500 Max = 2421840.295 + 0.5134948d*E [V.Zessewitsch, Tadj. Tsirk. N5, 1935., A.D.Bonov, Bud Mitt N38, 1955.]. Since 1960 - see Table. Secondary oscillation: Max (height of Max) = 2441037.33 + 12.997d*E. According to [P.O.Taylor, JAAVSO 6, N2, 56, 1977-78.], the magnitude in Max varies between 10.5 and 11.6 V.
