    Further analysis of this combined data set has shown very shallow
fading (<0.02 mag in average) at orbital phase 0.1.  There is no hint of
sharp eclipses seen on Aug. 16.  The light source responsible for the
Aug. 16 eclipse should have suddenly faded!  The phase 0.4 hump seen in
Puetz's data has not emerged yet.  This structure (possible late superhumps)
should have emerged suddenly.

    There is no indication of the slowing of the fading rate until the
Pietz's last run.
