Scientific paper

An analysis has been conducted for differential uvby observations of the Beta Cephei variable, Sigma Scorpii, which has shown four periodic components shortward of 0.5 day and a primary component that is much stronger than the others, as well as noticeably asymmetric. The secondary component is sinusoidal in shape. The two weakest short period components contribute very little to light variation. Results for the two strongest components are in essential agreement with those of van Hoof (1966).
