 ASASSN-20kw: new SU UMa-type dwarf nova

  Observations by Geoff Stone on Sep. 1 showed
an 0.2-mag superhump.  The period appears to be
rather long (~0.08 d).  On three nights before these
observations, Tonny Vanmunster also reported observations
without pronounced humps (probably with developing
humps on the final night).
