WZ Sge genuine superhumps!

Dear Colleagues,

    The analysis of the combined data on Aug. 4 (D. Starkey, Kyoto data,
G. Masi, 3218 points, still growing in number) has clearly shown the
presence of a signal with an amplitude of 0.10 mag and a period of
0.057197 +/- 0.000046 d.  The phase-averaged light curve at this period
shows sharply defined maxima, resembling those of "usual" superhumps
of SU UMa stars, and the phase 0.4 "shoulder", which had been the main
peak of early superhumps.  WZ Sge now started to show long-waited
superhumps.  The earliest strong evolution of this signature was observed
around Aug. 4.53 UT.  We have confirmed the all findings in
[vsnet-alert 6196, 6197 and 6199].

    Congratulations!

Regards,
Taichi Kato
