ASASSN-16iw: growing superhumps

   Josch Hambsch and Nataly Katysheva, Sergey Shugarov
have reported new observations.  The amplitudes
of superhumps have grown.  The current period
is around 0.0655-0.0660 d (stage A to B?).
The period before this growing phase was
similar (vsnet-alert 20086).  The object maye have
been continuously showing stage A superhumps
since our initial observations.
The object may have lacked the phase of early
superhumps.  In any case, the present period
suggests a candidate period bouncer and further
observations will clarify its nature.
