We performed simultaneous g'-i' photometry of a new WZ Sge star, OT J012059.6+325545 (vsnet-alert 12431, vsnet-alert 12346 ). The current bright outburst of the object was discovered by K. Itagaki on 30 Nov.(vsnet-alert 12341).

Our preliminary light curves of g'- and i'-band are shown in the figure. The object shows early superhumps with substructures in both bands. These substructures maight be dut to flickerings or eclipses. We continues photometric and spectroscopic observations of this dwarf nova. (A.A)
