OT J104411.4+211307 (=CSS100217:104411+211307) period of early superhumps
Maehara-san, Ian Miller and Kiyota-san have reported time-series
photometry. As reported by Maehara-san, double-wave modulations
resembling early superhumps of WZ Sge-type dwarf novae were present.
The full amplitude of variations was 0.04 mag (average), with minima
more prominent and sharper.
The most likely period 0.06301(4) d is unusually long for a WZ Sge-type
dwarf nova. This object might resemble long-Psh WZ Sge-type dwarf novae
(candidate period bouncers?) such as EG Cnc, OT J111217.4-353829 and
VX For. If the classification and period are confirmed, this object
would become the longest-Psh system among these objects (will be important
for study of CV evolution). Further detailed observations are strongly
