Delta(B) = 0.035m, Delta(U) = 0.07m. The Table gives the epoch of Max light. Observations may be represented by the periods 0.723d and 1.61553d [K.D.Rakosch, W.Fiedler, AsAp Suppl 31, 83, 1978., W.Schoeneich, G.Hildebrandt, W.Furtig, AN 297, 39, 1975.]. According to [C.Sezer, IBVS N1384, 1978.], in June - December 1977 Min = 2443337.4725 + 0.49925d*E, other periods are not satisfied by observations. According to [C.Blanco, F.A.Catalano, G.Strazzulla, AsAp Suppl 39, 127, 1980.], Max(U) = 2439751.28 + 0.617135d*E (1967 - 1971). SB, Max(Vr) = JD2443718.0 + 48.304d*E [M.Ouhrabka, J.Grygar, IBVS N1600, 1979.]. Photometric periods could not be found in radial velocities. |
