Scientific paper

UBV photoelectric observations of NY Cep which were made from 1982 to 1989 with GOTO 61-cm telescope at the Yonsei University Observatory are presented. The differential correction method of Wilson and Devinney (1979) was used to analyze light curves. An improved orbital period of 15.27566 days was determined. Data obtained confirm that NY Cep is a detached system. It is found that the secondary eclipse does not occur due to large eccentricity and inclination.
