ASASSN-19ax: interesting (secondary-dominated?) dwarf nova

   The 2019 January outburst looks like a superoutburst
(with a dip + rebrightening?).
Past outbursts were short and resembled normal outbursts.
The object is red and the amplitude was too small
for an SU UMa star (presence of a bright unresolved
companion?)

is too short.  Observations are requested.
