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.
