GCVS NOTE result

"VB Aab (AC 0.037"", 111deg, 1979.0, P = 9.219 yr [09535] "B 4.8m, 1.60"", 76deg, 1976.0 Min II 3.57. The range of combined light variation of the components AAb (SB 2, P = 7.989268d), AC, and B is given in the Table. Outside eclipses there are sinusoidal light variations of the system with A(V) = 0.05m due to pulsations of the component Ab [09535] with P = 0.30197d [09536] or 0.30145d [09537]. According to [08566] these variations were not observed between 1970 and 1976.
