Abstract: Analysis of the photometric behavior of the WZ Sge-type object PR Herculis during the 2011 outburst was carried out. The periods of "early" (0.05424d) and "ordinary" (0.054990d) superhumps were determined. The value of P_dot=4.7 10^-5, showing the rate of change of the period of "ordinary" superhumps during the superoutburst, was found.
