  A 6-hour photometric run confirms this fading trend is still under way.

  A period analysis using PDM, after removing the fading trend, yields
a weak periodicity centered at 0.0581 day.  It is likely weak superhumps
or late superhumps again became evident.  Follow-up observations to see
whether this fading episode indicates the termination of the current
already 43-day lasting spectacular superoutburst, or another "dip" or
some unknown sort of major fluctuation.
