SW UMa superoutburst, growth of superhumps

Dear Colleagues,

   We have further analyzed Tanabe-san's data.  The superhumps were growing
on Oct. 24, and reached an amplitude of 0.1 mag (possibly not fully grown)
on Oct. 25.  The profile of the superhumps is still atypical for usual
superhumps, suggesting that the waveform is still evolving.  Short-term
(minutes) modulations are superimposed, which may be QPOs (super-QPOs)
although they are not as striking as in the 1992 superoutburst
(Kato et al. (1992) PASJ 44, L215).  Further observations are strongly
encouraged.

Regards,
