ASASSN-16dt: fading following the early superhump phase

   Josch Hambsch has reported new observations.
Surprisingly, the object was recorded faint on
Apr. 20 (after a gap of 3-d observations).
Since this object had been showing early superhumps
until the last observation, this fading, instead
of a transition to ordinary superhumps, is rather
unexpected.  This object may undergo another full
superoutburst with ordinary superhumps as in
ASASSN-15jd, SSS J122221.7-311523 and OT J184228.1+483742.
See the most recent paper:
http://arxiv.org/abs/1604.06344
"ASASSN-15jd: WZ Sge-type star with intermediate superoutburst
between single and double ones"

   Continued observations of this object may detect
stage A superhumps and we may be able to know
the mass ratio of this suspected period bouncer.
