   Looking at Gianluca's original data, the light variation appears
similar to that recorded during the early fading stage of a superoutburst
(or a precursor) of short-Psh SU UMa stars (such as SW UMa).
The hump profile was complex and multiply peaked.
There also remains a possibility that we are observing the late decaying
stage of superhumps.  Further observations are strongly needed to
discriminate the possibilities.
