ASASSN-17qf: ordinary superhump

     Itoh-san and Kyoto U. team have observed the object. We can see
ordinary superhumps whose amplitude is 0.2 mag now. The object is
indeed a WZ Sge-type DN. Yesterday's data didn't show superhumps,
so this superhump may be stage A. The approximate period is 0.067 d.
This value strongly suggests that the object is a period bouncer.
     Further observations are, of course, encouraged.
