We have just received the data and analyzed them. The result more supports
a period close to the orbital period (rather than a longer period).
A combined set with the partially analyzed Kyoto data on July confirms
this finding. The light curve is quite similar to that observed in the
latter half of July 30. A new phase-averaged light curve is presented
on the VSNET WZ Sge page. Please note that the maximum of the main hump
has shown a slight negative phase shift, implying that the period has
decrease, rather than increased. Further observations are naturally
very strongly encouraged!
