1 GCVS Team mu = 0.100", P = 165.0deg. The epoch of light maximum is given. The mean brightness varies by 2 - 3m. Intervals of active light variation with amplitude up to 2m during maximal mean brightness are observed. During low activity intervals when amplitude is about 0.3m mean brightness is minimal; during this time the ellipsoidal light variations of the system are observed in the range 15.1m - 15.3m J with the elements Min = 2427889.6509 + 0.0697468256d*E [D.A.Allen, A.M.Cherepashchuk, MN 201, 521, 1982.]. The white dwarf rotation period is equal to the orbital period. There are flickerings. Spectrum description [G.Williams, ApJ Suppl 53, N3, 523, 1983., J.Patterson, K.Beuermann, D.Q. Lamb, G.Fabbiano, J.C.Raymond, J.Swank, N.E.White, ApJ 279, 785, 1984.].
