Photoelectric Vilnius Photometry of Stars in the Mega Proper Motion Field KA 10
Photoelectric seven-color photometry in the Vilnius medium-band systemis obtained for 87 stars down to V =~ 13.0 in the Kiev proper motionfield KA 10 (galactic longitude 137deg , galactic latitude--59deg . The size of the field is 1.4 square degrees. Foreach star, photometric spectral type, absolute magnitude, metallicity,and color excess due to interstellar reddening have been determined.These data, together with previous Vilnius photometry obtained in otherseven KA fields at high Galactic latitudes, will be combined withradial-velocity measurements and available proper motions to yield spacevelocities and to investigate kinematical and chemical properties of theGalactic disk in the direction perpendicular to the Galactic plane.

| 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.

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).
