[vsnet-alert 6334] WZ Sge giant humps emerging!

WZ Sge giant humps emerging!

Dear Colleagues,

   The analysis of Pietz's data and partially analyzed Kyoto data indicates
large-amplitude humps are emerging!   The humps had a smaller amplitude
in the early Kyoto data, but have grown to full-amplitude humps comparable
to those of superhumps.

   The phase is different from the "hump" observed on Aug. 17, and is
located close to the pre-eclipse phase.  The humps on Aug. 17 and 18 are
therefore of different nature!  We may be witnessing the regrowth of
superhumps, or other unexpected features.  The decline of the system
has substabtially slower on Aug. 18.  Beware of rebrightening(s)!!!
