 We report the discovery of a new eclipsing binary system USNO-B1.0 1629-0064825 (05h28m07.975s, +72d56m06.05s) with an unusual asymmetric light curve. The first maximum is much higher than the second one. Another feature of this curve is that the secondary minimum is shifted from the phase 0.5, the phase of the secondary minimum is phi=0.543±0.007. From the pure monochrome photometry, this star is very similar to the well known binary system V361 Lyr. We assumed that there is an accretion stream which impacts into the atmosphere of the star-accretor and forms a hot spot. All parameters needed for the General Catalog of Variable Stars were determined with corresponding error estimates. We have preliminary registered this variable star in the VSX, the star has got the name VSX J052807.9+725606.

Simbad object(s): USNO-B1.0 1629-0064825,
