    VB A (B 11.32mV, 27", 345deg; C 9.0mV, 62", 48deg); SB1
    (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 = 0.015P,
    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); A1 = 0.016m, A2 = 0.010m,
    A3 = 0.014m (1977); A1 = 0.010m, A2 = 0.014m, A3 = 0.023m
    (1980 - 81). 0.01m <= A <= 0.11m.
