Re: ASASSN-16hg: double superoutburst

     Josch Hambsch has reported new observations. The object has shown
the superhumps with the almost constant period but the amplitude is
decreasing. So the superhumps may be already stage B. If these superhumps
are stage B, the estimated mass ratio in my previous alert is incorrect.
     Further observations are encouraged to detect the stage transitions.
