We present photometric observations of the dwarf nova 1RXS J053234.9+624755.We performed a detailed analysis of the superoutburst that occurred in August2009. We found the superhump period to be P_sh=0.057122(14)days. Based on theO-C diagram we conclude that P_sh increased during the plateau at the rate ofdP_sh/dt=(9.24 +- 1.4) * 10^-5. Both the O-C analysis and evolution of thesuperhumps light curve favour the model in which superhumps originate in avariable source located in the vicinity of the hot spot. In addition, theevolution of the light curve suggests that the superhump light sourceapproaches the disc plane as the superoutburst declines. Detailed analysis ofthe superoutburst plateau phase enabled us to detect a signal which weinterpret as apsidal motion of the accretion disc. We detected additionalmodulations during the final stage of the superoutburst characterized byperiods of 104s and 188s which we tentatively interpret as quasi periodicoscillations. Estimations of A_0 and A_n are in agreement with the dependencediscovered by Smak (2010) between the amplitude of superhumps and the orbitalinclination.
