Scientific paper

Photoelectric observations of KR Persei are presented. A solution of the light curves based on the Russell (1952) model yielded a value of 0.96 for the ratio of radii, 0.324 for the radius of the larger component, and 83.7 deg for the inclination of its orbit. The binary orbit appears to have a small eccentricity, which is estimated to be 0.009. The corresponding longitude of periastron of the smaller star counted from its ascending node in the direction of its motion is 160 deg.
