1 GCVS Team EA/SD. SB1. Min II 10.60. P var. Min = 2424434.5071 + 3.3054975d*E + 0.1215d* sin (0.0543deg*E + 186.8deg) (JD2411400 - 33300) [A.Szczepanowska, AAb 2, 134, 1955.]; Min = 2437375.4923 + 3.3055069d*E + 5.3d*10**(-8)*E**2 (JD2437375 - 41000) [P.Broglia, F.Marin, AsAp 34, 89, 1974.]; since JD2440000 - see Table. The primary component is a DSCTC variable [P.Broglia, F.Marin, AsAp 34, 89, 1974.] with A <= 0.05m B. According to [M.S.Frolov, E.N.Pastukhova, A.V.Mironov, V.G.Moshkalev, IBVS N1894, 1980.], the pulsational period is possibly synchronized with the orbital motion and remains practically constant (0.066458d) during a long time interval.
