Scientific paper

From images of the spectroscopic binary beta Sco A, formed by the Jovian atmosphere during its 1971 May 13 occultation by Jupiter, the angular separation of the binary components was found to be 0.001496 plus of minus 0.000018 arcsec. The combination of this measurement, the elements of the spectroscopic orbit, and the parallax determination of Bertiau (1958) yields masses of 21.1 plus or minus 3.2 solar masses for the primary (B0.5 V) and 12.7 plus or minus 1.9 solar masses for the secondary. New observations are suggested for improving the accuracy of the mass determinations.
