   Just have a look.

   The long-term light curve very much resembles an SU UMa-type
dwarf nova with a short supercycle.  ER UMa-type imposter?
The speed of decline strongly suggests an SS Cyg-type object.
If it is indeed an SS Cyg-type object, my suggestion
in PASJ 66, 30 (in response to Mroz et al. 2013, who reported
a large number of "SU UMa-type" objects between ER UMa stars
and ordinary SU UMa stars) is substantiated.
