OT J000938.3-121017: shortening of the superhump period

   Maehara-san and Kyoto team (observer: Ohshima-san) have reported further
observations.  The data indicate remarkable shortening of the superhump
period.  The mean period until Oct. 10 has been 0.08934(2) d.
The decrease of the period was prominent between Oct. 8 and 10, when
a stage B-C transition may have occurred.
The overall (global) Pdot has been -60(7)*10^(-5).  It is very important
to see whether this tendency continues, or it was a stepwise change.
