Scientific paper

Four-color uvby observations of the short period RS CVn system WY Cnc were made in March 1986. Three times of priminimum were determined. With the starspot assumption, the photometric distortion waves were analyzed of the b and y observations, and of Chambliss' (1965) B and V observations, respectively. The analyses were based on the W-D program of 1983 edition and the differential correction computing code for spot parameters designed by Zhai and Chen (1988). Two spots were found on the primary component in each of the two epochs. The photometric results show that WY Cnc is a main sequence detached system.
