ASASSN-17es: early superhump period

     Josch Hambsch has reported further observations. The object was 15.7 mag
on April. 22. The object has continued to show double-wave modulations, so
these are early superhumps indeed. The updated period is 0.066623 (5) d, and
the amplitudes are 0.05-0.06 mag.
     The superoutburst was detected on April 10. Thus we can see stage A before
long. Further observations are encouraged.
