ASASSN-18ach: new long-period SU UMa-type dwarf nova

   Berto Monard, Josch Hambsch and Kyoto U. team have
reported observations.  The object now shows superhumps.
The period is not yet well determined (probably around
stage A-B transition).  The most likely period is
0.0971(1) d.  Further observations are needed to
study the period evolution.
