SW UMa short unexpected rebrightening

Dear Collagues,

    Some of the VSNET SW UMa collaboration team have continued observation
of post-superoutburst SW UMa.  Among them, Elena Pavlenko (Crimea) and
Sergei Shugarov (Moscow) have provided excellent post-superoutburst data
on this star.  They have caught a short brigtening of by ~1 mag lasting
at least 2 hours, in their time-series on Mar. 14.  An indication of
the start of the rise could be traced in the preceding Kyoto data.
The object returned to its normal magnitude on the next night.
This phenomenon can be a some variety (with an unexpected evolution) of
post-superoutburst rebrightening.  The present observation stresses the
importance of continuing observations of post-superoutbursting SU UMa-type
dwarf nova.

    The entire light cuvre is seen at:
