SW UMa: post-superoutburst behavior

Dear Colleagues,

   We have analyzed Torii-san's Nov. 12 and 13 observations and Kyoto data.
The object reached a post-superoutburst state (still brighter than the
true quiescence) and very gradually fading.  On November 12, short-period
variations became less prominent.  On November 13, the variation became
stronger again (0.1-0.4 mag), some of which look like late superhumps.
In case SW UMa undergoes a post-superoutburst rebrightening (as in other
short-period SU UMa stars), we can expect such a phenomenon within a few
days.  Close monitoring and intensive coverage is still needed.

Regards,
