Re: ASASSN-19xw is a new SU UMa (or WZ Sge)-type dwarf nova

   Long-waiting time for ordinary superhumps and
rapid fading in the initial phase point to a WZ Sge star.
The initial phase was the viscous decay phase.

   The large amplitude and the light curve looking like
to a fast nova are very similar to V592 Her. See:
