   These variations outside primary eclipses look like to be
the combination of secondary minima of the irradiated secondary
and ellipsoidal variations, rather than superhump-like variations
(the identification would require model fitting).
Unfiltered CCD photometry of high-inclination long-Porb DNe
sometimes show this kind of orbital variation.

   Nevertheless, the system clearly show prominent eclipses even
during a bright outburst.  The signature of the hot spot looks
like to be weak (overall profile very different from that of U Gem).
