Remark:
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) [09348]. In 1979 sinusoidal light oscillationswere observed in the range 10.20m - 10.27mV:Min = 2444037.576 + 4.378d*E [09349]. In 1974 - 76 suchperiodicity was not observed [09350].
