A close double star on Orion's right side; where a line from Orion's belt towards Aldebaran passes it at about 4½° below Bellatrix. A 8, silvery white; B 10, grey. This delicate object is 52 ♅ I., and was placed by Σ. in his First Class, "plurium maxima." There are few close double stars whose fixity for upwards of half a century has been more satisfactorily proved than this, the other measures being as follows :♅. Pos. 322°48' Dist. 2".0± Ep. 1782.76
S. 320°48' 2".98 1825.06
