OT J230425.8+062546: emerging superhumps

   Shiokawa-san has reported observations on two nights.  As reported by
Arai-san, significant superhumps were observed on Jan. 4.  Although the
period is still difficult to determine, the amplitude was 0.05 mag on
Jan. 4.  The profile was more irregular (possibly slower rise and
faster fade, as in early superhumps) and the full amplitude was 0.05 mag.
The present superhumps are likely stage A superhumps.  The appearance
of superhumps is relatively early (unless the true maximum of the outburst
was undetected for a long time) for a WZ Sge-type dwarf nova.
Further observations are encouraged!
