OT_J023839.1+355648: updated superhump period

   The superoutburst of OT_J023839.1+355648 still continues
(observers: Maehara-san, Nakajima-san and Kyoto team).
The updated mean superhump period is 0.053667(5) d.
The amplitudes of superhumps decreased since Nov. 4, but
showed a regrowth on Nov. 18.  Since then the profile of the
superhumps became flatter (and double-humped).  There was relatively
small variation in the superhumps.  The overall behavior (long duration
of the superoutburst, delay in appearance of ordinary superhumps)
is consistent with an outburst of a WZ Sge-type dwarf nova.
