WZ Sge: very slow fade continues

Dear Colleagues,

    We have received another set of high-quality data from B. Martin.
We are also intensively analyzing the newly acquired Kyoto data.

    Both observations show a stedy trend of slow decline (up to 0.1 mag/d)
after the fading of the 12th rebrightening.  Hump features are still
impressively seen.  Although it is hard to expect what comes next in
subsequent days, the star may be entering its final decline stage, or
may undergo a next rebrightening after the present "jitter" period.
Further observations are strongly encouraged, since this is the first
time in the long history of WZ Sge, that such a stage of the outburst
can be sufficiently recorded -- we know almost nothing of this stage
of the outburst in 1978-1979!

Regards,
Taichi Kato
