1 GCVS Team VB (B 15m, 5"). The range of combined brightness variation is given. It is not excluded that it is the component B that is variable. Slow variations of mean brightness in the range 10.555m - 10.570m B are superimposed by sinusoidal periodikal ones with P1 = 1.3608d (A1 = 0.0037m) and P2 = 0.8055d (A2 = 0.0032m).
