1 Otero, Sebastian Alberto Non-eclipsing system.
2 GCVS Team An unique close binary. Porb = 13.4192d [D.G.Monet, ApJ 237, 513, 1980.]. Epoch of Min I is given close to the epoch of one of conjunctions. Min II - Min I = 0.58P. Maxima are very sharp. Max - Min II = 0.25P. It is not excluded that the star is an eclipsing one with physical variability of components, but eclipses, if they exist, cause only a very small part of the observed light variations. Range of light variations is given according to [E.Kollnig-Schattschneider, AN 271, 85, 1940.]. As a rule the amplitude is close to 0.1m.
