OT J122221.6-311525 rise to rebrightening

   Josch Hambsch observed the rising part and the maximum
of this rebrightenings.  The rise was relatively slow, suggesting
an inside-out type outburst.  Superhumps were also superimposed.
A combined analysis suggests a period 0.06285(9) d or 0.06692(9) d,
which are on the longer side of the range of the orbital period
inferred from spectroscopy (ATel #4716).  Further observations
are strongly encouraged because we expect to see additional
rebrightenings.
