The WZ Sge-subtype of dwarf novae is characterized very rare and large amplitude outbursts, very short orbital periods (in average, of 1.5 hour), a small mass transfer from the secondary (possible brown dwarf) and superhumps during the superoutburst. We present multicolor CCD photometry during superoutburst of a new cataclysmic variable TCP J10240289+4808512 (= ZTF19aavnxej), outbursted on May 25, 2019 and was classified as a new SU UMa or WZ Sge-type system. The analysis of our data revealed the presence of ordinary superhumps with the period closed to 0.064 d. The common light curve of superoutburst was constructed and the duration of superoutburst was estimated. The evolution of superhumps profiles, its amplitude and the superhump period, connected with the changes in accretion disc around the white dwarf, is analysed. Two-colour diagrams together with the superoutburst evolutionary tracks of the nova are presented. The results of our oservations are discussed.
