The results of three-color BVR photometric study of a recently discoveredunusual binary system VSX J052807.9+725606 = USNO-B1.0 1629-0064825 arepresented. This system is very similar to V361 Lyr, which was assumed to beunique. We confirmed a strong asymmetry of the phase curve and found thewavelength dependence of the amplitude. This is interpreted by a "directimpact" model with a "hot spot" in the atmosphere of the accreting component.Color temperatures are determined. Characteristics of the "hot spot" areestimated. We also calculated the new ephemeris for VSX J052807.9+725606.
