SDSS J133941.11+484727.5: post-superoutburst superhumps

   Ian Miller has reported further observations.  The amplitude of
superhumps again decreased, and the variation appears to reflect
a beat phenomenon between Psh and Porb.
The superhump period during this interval has been 0.058170(5) d
and mean amplitudes of 0.15 mag.  The orbital modulation has a mean
amplitude of 0.09 mag, and the overall variation seems to be expressed
by the combination of these variations.  Longer baseline of observation
will reduce the ambiguity in decomposing these periods.

   Further detailed analysis will be presented by Ohshima-san.
