Photoelectric measurements of lunar occultations. VIII
Photoelectric timings are reported for 276 lunar occultation eventswhich were observed between March 1975 and February 1976. The timings(in UTC) are based on Loran G equipment of a lunar laser-ranging groupor on WWV signals. Angular diameters are determined for HR 5301, HD176124, Chi-1-Orionis, and HR 601. Twenty cases of possible or actualdouble stars, including Beta Capricorni, are noted along with oneprobable triple system (51 Piscium). Several technical and computationaldifficulties encountered in this program are discussed.
