Remark: The epoch of Min for periodic (P = Porb) light variations with A <= 1m B is given. Min II is present. B - V = 0.0 in Max light, +0.5 during an eclipse; U - B = -1.1. Circular polarization in B light -9% to -35%; linear polarization 0% - 13% with a sharp Max near Max light. Rapid changes (A = 0.03m, f = 0.4 - 0.8 Hz). The mean light level and the light curve shape var. During the low state (B ~19m) the light variability with porb disappears, emission lines occur only during 10% of Porb, IR excess is noted. Soft X-ray source, var. Emissions of H, HeI, He II, NIII, FeII.
