ASASSN-22jz: new WZ Sge-type dwarf nova

Berto Monard has reported observations on two nights. The object was fading rather rapidly (0.3 mag/d), probably in viscous fading phase. Although there were much irregularity, I could detect a period of 0.05404(4) d (double wave, 0.035 mag). Although the profile is not very typical for early superhumps, the period appears to be real based on the appearance of one-day aliases. The rather unusual profile of early superhumps a result of their low amplitude and overlapping irregularity. Considering the outburst amplitude and peak M_V, this object can be identified to be a WZ Sge star.
