OT J230425.8+062546: superhumps update

   Itoh-san, Shiokawa-san, and Crimean Astrophys. Obs. team (Elena Pavlenko
and Oksana Antonyuk) have reported further observations.  The data perfer
a shorter alias with a slight period evolution.  The mean period has been
0.06293(3) d.  Interestingly, the amplitudes of superhumps have been
slightly increasing.  Such a slow evolution of superhumps at this stage
is rather atypical.  Continued observations are encouraged.
