Occultation observations made with the 0.76 m reflector at McDonald Observatory are presented, for 319 events occurring between Jan. 15, 1981 and Feb. 7, 1982. One table reports timings, and a second records observations of 16 double stars, in particular, Nu Gem observations reveal that the two close components are similar in color. This allows an estimation of individual visible magnitudes (near 4.60 and 5.32) suggesting that the secondary is a late B-type main-sequence star. SAO 158929 observations reveal systematic differences in angular diameter values. Of the 16 observed double stars, 9 appear to be new discoveries, including SAO 93067, SAO 94595, and SAO 98770. A third table gives fully darkened angular diameters for the stars SAO 158929, SAO 77516 Y Tau, and SAO 119035 Nu Vir.
