1RXS J053234.9+624755 superhump evolution

   Pavol A. Dubovsky has reported a big set of observations
(cf. vsnet-alert 11484).  The combined data have very clearly illustrated
the superhump evolution.   The period derivative was positive
(dot(P)/P = 10.0(1.0)*10(^5)) before Sep. 2 (terminal stage of the
superoutburst plateau), when the object underwent a stage B-C transition.
The object showed stage C superhumps with a period of 0.05698(2) d.
No anomaly was detected in the O-C diagram despite the presence of
a precursor.  This result has confirmed the observation during the
2005 superoutburst (Imada et al. 2009).
More detailed analysis is in progress.
