WZ Sge: humps and eclipses on Aug. 29

Dear Colleagues,

   A quick look at the partly analyzed Kyoto data on Aug. 29 (around 29.55 UT,
just before the bottom of the fading) has shown only weak (0.05 mag or less)
presence of the hump structure, which had been evident on Aug. 28-early 29.
The main hump is now observed at phase 0.5 (the main peak before the eclipse
had almost disappeared!).  Shallow, slightly broad, eclipses are also present,
at slightly earlier than the predicted times.  There must have been a
subsequent dramatic change in the hump and eclipse profiles, as judged from
the description and preliminary data from D. Starkey.  Please follow the
evolution of humps and eclipses, and the fifth rebrightening, as closely as
possible!

Regards,
