OT J043112.5-031452: period variation during stage B

   My analysis has yielded Pdot = +9.1(1.1)*10^(-5) for stage B superhumps
(up to Dec. 11).  Mean superhump periods for stage B and C are
0.06756(1) d and 0.06731(3) d, respectively.
There have been a very strong indication of a beat phenomenon during stage B
(as was observed in HT Cas and IY UMa).
The profiles and depths of eclipses have been changing.
I hope Ohshima-san could provide more detailed description and analysis of
these variations!
