OT J230425.8+062546: update period of superhumps
Itoh-san and Maehara-san have reported further observations.
We have two candidate aliases of 0.06739 d and 0.06312 d, the former
more strongly supported by Maehara-san's new observation.
In either period, the variation of the period has been very small
(Pdot an order of 1*10^(-5)), and we may be observing a WZ Sge-type
star with a small Pdot (but with a long Psh), or stage C superhumps.
The amplitudes of superhumps have been about 0.10 mag.
Since this object may have rather unusual properties (in Psh amd Pdot etc.),
further intensive observations are encouraged.
