Semiregular light variations with the mean cycle 97d; mean brightness varies with the cycle ~4700d [S.Gaposchkin, HA 118, N20, 1952.]. There are also a cycle 725d [L.Luud, M.Ruusalepp, J.Vennik, Tartu Publ 45, 113, 1977.], rapid oscillations (A <= 0.25m U) and flares [H.M.Johnson, J.C.Golson, ApJ 155, L91, 1969.]. It is not excluded that the system is an eclipsing one [C.Y.Shao, W.Liller, BAAS 3, N4, 1, 443, 1971.]. |
