Dear all,

   The analysis of superhump light curves up to April 25 gives
a significantly shorter period (average 0.05431 d).
It may be that genuine superhumps are now experiencing a stage
of rapid period evolution.  The nominal fractional period excess
becomes 1.9%.  More detailed timing analysis is being undertaken
by Imada-san, and will be issued shortly.
