It should be interesting to have any confirmation of this. 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! Regards, Taichi Kato VSNET Collaboration team
