VB A (B 12.74mB, 10", 260deg, 1949); mu alpha = -0.065s, mu delta = -0.46". Dark companion (A = 0.0206", P = 45 yr, E = 0.5) [P. van de Kamp, S.L.Lippincott, BAAS 12, 455, 1980.]. In 1979 sinusoidal light oscillations were observed in the range 10.20m - 10.27mV: Min = 2444037.576 + 4.378d*E [B.R.Pettersen, AJ 85, 871, 1980.]. In 1974 - 76 such periodicity was not observed [F.M.Mahmoud, K.Olah, IBVS N1943, 1981.]. |
