Min I = 2420980.8093 + 0.333638880d*E (JD2416000 - 21000); Min I = 2420980.8093 + 0.333636993d*E (JD2421000 - 33000) [E.J.Woodward, HC N446, 1942.]; Min I = 2435918.4169 + 0.33363832d*E (JD2433000 - 41000) [B.Cester, Trieste Publ N359, 1967.]; since JD2441000 - see Table. The light curve shape, including depths of minima, var. A moving wave with Delta(m) = 0.025m y and P ~1100d [E.F.Guinan, S.-I.Majafi, F.Zamani-Noor, IBVS N1662, 1979.] was noted. A flare (Delta(m) = 1.5m, lambda 3300 A, delta(lambda) = 50 A, JD2438511.7, delta(t) = 7 min) was announced [L.V.Kuhi, PASP 76, 430, 1964.]. The system contains gaseous streams, dark spots on the surface of the components. H and K CaII emission. |
