ASASSN-17qf: possible ultra-short period modulations

     Josch Hambsch and Kyoto U. team have reported the observations.
The object is about 15 mag now. The light curve indeed showed some
modulations. The most likely period of the modulations is 0.033 d or
the double period of 0.066 d. The object can have an ultra-short orbital
period, but the long-term observations is not enough (only one night).
     Confirmation is strongly encouraged.
