SB (Porb = 0.1336d [D.P.Schneider, P.Young, S.A.Shectman, ApJ 245, 644, 1981.]). Quasiperiodic fadings of different amplitude: Min = 2425558 + 455.5d*E (JD2425500 - 30100); Min = 2430113 + 325.3d*E (JD2430100 - 36900); Min = 2436944 + 357.8d*E (JD2436900 - 44100) [W.Wenzel, B.Furhmann, MVS 9, H.6, 1975, 1983.]. After JD2444100 the mean brightness level became fainter by 5m; outbursts with an amplitude up to 3m of 1 - 2 months duration are observed [I.L.Andronov, S.Yu.Shugarov, IBVS N2418, 1983.]. During the bright level of light, flickering up to 0.4m in 5 Min in U bAnd is observed [M.F.Walker, PASP 66, 71, 1954.]. Soft X-ray source. B - V: 0.00 +- 0.40; U - B: -0.86 + -1.30. |
