ASASSN-17hw: new WZ Sge-type?

     Tonny Vanmunster, Stephen M. Brincat, Itoh-san and Josch Hambsch
have reported new observations.
     The outburst occurred on June 20, and the object had not shown the
superhumps. However, clear superhumps were detected on July 2. These
behaviors suggest that the object is a new WZ Sge-type DN. The object
has shown the growing amplitude of superhumps like stage A now and
the period seems around 0.06 d.
     Further observations are strongly encouraged.
