An Evolution of Superhumps of New WZ Sge-type System in Leonis". S. Shugarov, AI SAS We present our CCD observations of a new WZ Sge-type dwarf nova in Leonis during its superoutburst in 2010 and in quiescence in 2016-18. The light curve shows one rebrightening. The evolution of nightly light curves of early, ordinary and late superhumps are presented. The mean superhumps period 0.06053 days was determined and period changes were detected. The possible value of orbital period in quiescence, clouse to 0.059 days, was suspected.
