WZ Sge: change of (super)hump profiles

Dear Colleagues,

    The analysis of the Kyoto July 29 run has shown a substantial change
in the profile of (super)humps.  The regular pattern of early superhumps
has been taken over by more irregular-looking variations.  There is
emerging evidence of humps, with amplitudes comparable to those of early
superhumps, at phases significantly offset from the original early
superhumps.  Such a pattern can be also found in Lew Cook's data taken
last night, but was never met in earlier nights.  The profile of early
superhumps is strongly, and rapidly changing.  Further detailed observations
are most urgently requested.  More detailed information will be presented
by Ishioka-san and Uemura-san.

Regards,
