A long-term project (ten-year ; 1982-92) for the photoelectric observation in the UBV passbands of selected eclipsing binaries with P¡Ã10 days has initiated at Yonsei University Observatory using 40-§¯ and 61-§¯ reflectors. The instrumentation used and the observation techniques and the reduction procedures applied to this investigation are described. Out of 39 program stars, successful results have been obtained during our first two years for the 11 stars listed below, with the orbital period in days in the parenthesis, and the incomplete light curves of these stars are presented. SX Cas (36.57) AQ Cas (11.72) UU Cnc (96.71) RY Gem .( .9.30) V373 Cas (13.42) NY Cep (15.28) RX Cas (32.32) V396 Cas (15.28) ZZ Cnc (25.60) Zet Aur (972.2) Eps Aur (9885.) For the rest of the stars, the observations made in the first two years are not sufficient to sttempt any meaningful light curve construction ; some of the data are too fragmented and others show large scatter.
