1 GCVS Team VB A (B 8.8m, GO III - IV, 1.60", 269.4deg, 1977). SB1 (P = 2983d [D.B.McLaughlin, S.E.A. Van Dijke, ApJ 100, 63, 1944.]). Epoch of Min brightness is given. The deepest minima (corresponding to the middles of the descending branches of the radial velocity curve) are satisfied by the elements: Min = 2429355 + 2984d*E [H.van Schewick, AN 279, 65, 1950.].
