WZ Sge: markedly reduced hump amplitude

Dear Colleagues,

   We have received new data from A. Oksanen, T. Vanmunster (4 nights,
including a revision of the previous data) and J. Pietz (3 nights, including
addition/updates to the previous data).  We have also completed the analysis
of the Kyoto data up to now.

   The data clearly show that the hump amplitude and eclipse depth reached
a maximum on mid Sep. 28 (UT), and quickly decreased since then.  As reported
by J. Pietz, the light curve has become surprisingly flat (confirmed by
independent observations by A. Oksanan and T. Vanmunster).  Eclipses have
also become less apparent.

   The object is expected to show "double" or "triple" hump structure
around today or tommorrow, and the hump feature will become strong again
around Oct. 2 or 3, unless a new rebrightening disturbs the present
tendency.

Regards,
Taichi Kato
