OT J002656.6+284933: positive Pdot and stages A/B

   Tamas Tordai and Sergey Shugarov have reported new
observations.  It has now become confident that
this object displays a positive Pdot characteristic
to stage B superhumps.  The current Pdot = +14(2)*10^(-5).
Before these stage B superhumps, the superhump amplitudes
apparently grew, indicating that stage A superhumps
were indeed recorded.  If we can know the orbital
period or the period of post-superoutburst superhumps,
we can determine the mass ratio of this very unusual
object.  Please continue your observations and extend
them to post-superoutburst (and a potential rebrightening?)
