ASASSN-16dt: already stage B superhumps?

   Kyoto U. team, Berto Monard, Josch Hambsch and
Gordon Myers have reported new observations.
The object apparently shows stage B superhumps,
rather than stage A, since the amplitudes are
now decreasing.  By using this identification,
stage A superhumps were likely recorded up to
Apr. 27 (rising phase of the second superoutburst).
It may be that the superhumps started to grow
during the "dip"-like phase after the initial
superoutburst.  The period determined from these
observations is 0.06502(3) d, and q=0.034.
The development of superhumps is rather unusual
and these values may be subject to change.
