ASASSN-17cn: new WZ Sge-type dwarf nova

   Berto Monard and Itoh-san have reported observations.
The most recent data by Monard (since March 5)
showed ordinary superhumps.  The period was
0.05384(3) d and a mean amplitude was 0.11 mag.
An analysis of earlier observations yielded
a weak signal at 0.0530 d (early superhumps?).
Further observations are strongly encouraged.
Since the amplitude of ordinary superhumps is
small, these superhumps still may be stage A ones
(or the mass ratio is small).
