ASASSN-18wa: new WZ Sge-type dwarf nova?

Tonny Vanmunster, Tamas Tordai and Geoff Stone reported observations.
The object shows double-peaked modulations like early superhumps. The
amplitude is 0.02 mag and the period is 0.05441(3) d. Double-peaked
modulations and the short superhump period suggest that the object is a
WZ Sge-type dwarf nova. It is worthy of note that the short early superhump
period indicates the object exists on or below the period minimum.
Further observations are encouraged.
