Photoelectric light curves of the ? Canis Majoris type variable, Sigma Scorpii, were obtained nearly simultaneously with a series of radial velocity measures made by Struve and collaborators. The photoelectric results show the existence of a beat period of 8d.028 superposed on the known short period variation of 0d.246846. The star is shown to be brightest and bluest when at or near minimum size.
