UBVRI light curves of Dwarf nova Peg 2010

We present our UBVRcIc CCD photometry of a new dwarf nova OT J213806.6+261957 in Pegasus, discovered during its superoutburst on May 6, 2010 and classified as a WZ Sge-type star. In the term May 15 - November 27, 2010, we obtained more than 10000 CCD observations of the nova. Twocolour diagrams together with the superoutburst evolutionary tracks of the nova are presented. The analysis of our data revealed the presence of ordinary superhumps with the mean period of 0.055106d and late superhumps with the period of 0.05490d. We calculated the orbital period of the dwarf nova Pegasi 2010 to be 0.0542+/-0.005d and estimated the mass of the red dwarf component in the binary as 0.09+/-0.01M_{sun}.
