OT_J104411.4+211307 rapid fading!

   Josch Hambsch and Enrique de Miguel Agustino have reported new observations
on March 9-10, indicating that the object has entered the rapid fading stage.
Superimposed superhumps are still visible, but with smaller amplitudes
with likely double peaks.

   There appears to have been a transition to a shorter superhump period
(stage B to C transition?) around this epoch.  This phenomenon needs to be
confirmed by further observations.  The mean superhump period since March 6
has been 0.06018(1) d.

   Since this object is expected to show rebrightening(s) (even multiple),
continued observations are strongly encouraged.
