GCVS NOTE result

"VB A (B 11.32mV, 27"", 345deg (Porb = 12.0968d). Eclipsing system with a pulsating primary component of BCEP type. Depth of Min I 0.05mB. "Min I = 2444909.4339 + 12.096816d*E d = 0.000P. Simultaneously pulsations are observed with the periods P1 = 0.169170d, P2 = 0.170770d, P3 = 0.181692d [09346]. The corresponding amplitudes of pulsations vary. The values of the amplitudes in B system are as follows: A1 = 0.046m, A2 = 0.024m, "A3 = 0.022m (1952 - 1965) "A3 = 0.014m (1977) (1980 - 81). 0.01m <= A <= 0.11m.
