WZ Sge: new data and nightly averaged magnitudes

Dear Colleagues,

   We have received new data from K. Morikawa, T. Hynek, M. Moilanen,
T. Vanmunster, J. Pietz, and our new data at Kyoto and Ouda.  The data
depict all the recent important changes (second rebrightening, deveolpment
of superhumps and their progressive phase shift, eclipses).  We are
undertaking in more elaborate time-series analysis.  We have also put
on the VSNET WZ Sge page the most recent summary of the light curve.
(Phase-averaged curves will appear later).

   As a guide to observers, we summarize updated preliminary nightly averaged
magnitudes (some data esp. around the "dip" and the latest data have not
been yet incorporated, as earlier described).
