Abstract
During the four last years (1978–1981), some close binaries of W Ursae Majoris type have been observed from the National Observatory of Athens.In all cases a two-beam, multi-mode, nebular-stellar photometer has been used, attached to the 48-inch Cassegrain reflector at the Kryonerion Station.The observed systems are: 44i Boo, VW Cep, AB And, BV Dra, BW Dra, U Peg, V508 Oph. Especially VW Cep and 44i Boo, are very interesting objects; in addition to the light curves that have already been published (Rovithis and Rovithis-Livaniou, 1980–1981), other observations were obtained during the last year and are now at computational stage. The observations of these two systems will be continued during the next years.
