Abstract
Photographic observations of eclipsing variables of the W Ursae Majoris type were included in the program of the Abastumani Astrophysical Observatory. At the present time the program of Observations covers the following stars: OO Aquilae, AP Aurigae, RZ Comae Berenices, UX Eridani, WW Eridani, EX Lyrae, BB Pegasi, ZZ Persei, AG Virginis, AH Virginis and several others. Observations are carried on the Newtonian focus of the 13-inch reflector, constructed at the State Astronomical Institute, Leningrad. The optical data of the reflector are as follows: diameter of the parabolic mirror D=330 mm; focal lenght F=1655 mm; light ration =1:5; diameter of photometric field =ca.40' (25 mm in linear measure), plates: 5.8X5.8cm. Several notes devoted to the individual stars of the W Ursae Majoris type are given. Each note contains the computed elements of the given variables, its photographic light-curve, table of the brightness etc. In the tables mentioned, if it is not indicated otherwise, the moments of observations are given in heliocentric Julian dates (J.D.) reckoned from the mean Greenwich noon. The brightness of the comparison stars is usually derived from the plate, on which the area of the given star and one of the Kapteyn's Selected Area (KSA) is taken. The brightness of the stars of the KSA is taken from the work by Parkhurst and Farnsworth. January, 1937
