Аннотация: We present our CCD observations of a new WZ Sge-type dwarf nova in Draco (PNV J18422792+4837425) during its superoutburst in 2011. At the plateau of the superoutburst of this unique object, superhumps with very small amplitude were detected. During a decline of brightness, the unusual long rebrightening followed by a short one were observed. The evolution of the multicolour light curves during all stages of the superoutburst is described. The superhumps periods were determined. We suggested the existence of the late superhumps at the final decline of the superoutburst, which lasted about 170 days.
