Observations of the occultation of Beta Scorpii on July 8, 1976, made with four telescopes at McDonald Observatory are discussed and reduced to a form suitable for combination with results from elsewhere. Five components of this star are identified, and estimates made of their individual magnitudes. The observed times can be reconciled with the deduced parameters for the different telescopes taking lunar slopes into account. The positional data for the closely separated components seem very tractable, but there may be difficulty with the timings of the two main components, one of which shows a large residual. This is neither due to instrument error nor entirely accountable by the published limb deviations from the Watts (1963) tables.
