Title: New CCD photoelectric observations of the contact binary GSC 02013-00288

Abstract: We present the first set of complete light curves in the B, V, R and I bands observed photometrically in 2013 for the contact binary GSC 02013-00288 (=IK Boo) after its discovery without a filter. New ephemerids were determined. The O-C diagram shows a decrease in its orbital period by a rate dP/dt = -1.979 × 10^-7 day/year.
