Ellipsoidal and reflection variability superposed with an amplitude of 0.5 mag. at quiescence (mean V= 12.9 - 13.4). B-V= 1.09 (2008BaltA..17..293H). Maximum given is from a single photographic plate in 1976JAVSO...4...64L. The rest of the data is consistent with an outburst maximum around V= 10.5. |
