Star is fainter component of the visual triple system A.D.S. 1630. The pair B-C is unresolved on the slit of the Perkins Observatory spectrograph. It is believed that B is the spectroscopic binary. The visual components appear to be physically connected, and the system is therefore at least quadruple.
