Abstract:
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_☉.
