New light curves obtained in UBV and R are presented for the short-period RS CVn-like binary WY Cancri. The system exhibits a distorted light curve at phases near second quadrature, and on one night excess light was seen at these phases. A light-curve-synthesis solution yields parameters that generally agree with the earlier transit model of Awadella and Budding (1979), although the derived temperature of the secondary is higher and its limb darkening lower. The recent observations fail to indicate any period change.
