First experience in automatic spectral classification related to the MEGA program The results of automatic quantitative spectral classification of starsin field No. 10 (alpha-1950 = 1 h 18 m, delta-1950 = + 3 deg 13 min) ofthe MEGA program are presented. Some tentative stellar-statisticalresults are discussed.
Photoelectric observations of lunar occultations. XII Occultation observations of 414 events observed between 6 July 1979 and4 September 1980 with the 0.76-m telescope of McDonald Observatory arereported. Timings and data on double stars are given. Angular diameterinformation in six cases is included. The stars concerned with their runnumbers are: SAO 161754 (5270); 94027 (Alpha Tau) (5319, 5381, 5454);159370 (Gamma Lib) (5325, 5571); 162413 (43 Sgr) (5332); 97472 (3 Cnc)(5414); and 93955 (Theta Tau) (5445).
