ASASSN-13bz: SU UMa star (or even WZ Sge)

Itoh-san detected superhumps on Dec. 3 (amplitude 0.12 mag). The period from single-night baseline is 0.059(1) d. I suspected this object to be an SS Cyg star based on the initial fading rate (0.2-0.4 mag/d) and the lack of superhumps, but this may have been a viscous decay phase of a WZ Sge star (considering the rarity of outbursts). Early superhumps may have not been present simply based on a low inclination.
