ASASSN-16dt: stage A superhumps, likely period bouncer

   Enrique de Miguel has just reported further data.
The object has further brightened and now in plateau
phase.  Superhump were well present.  Using Monard's
and de Miguel's data, the period is 0.06489(5) d.
The period excess of stage A superhumps implies
a low mass ratio of 0.03, although this value is
still uncertain due to the short baseline of stage A
superhumps.  The object appears to show "type-E"
superoutburst (double superoutburst) and is likely
a period bouncer.  Intensive observations are 
encouraged.
