ASASSN-15uj: ordinary superhumps

   Josch Hambsch and Berto Monard have reported new
observations.  The object apparently started to show
stage A superhumps on Dec. 29.  The superhumps have
now become stable (stage B).  The current period is
around 0.0558 d.  The period of stage A superhumps
was 0.05679(4) d.  This superhump excess corresponds
to q=0.07.  The relatively slow growth of superhumps
is also consistent with the low mass ratio.
