TCP J21040470+4631129: modulations in fading tail

     Tonny Vanmunster, Tamas Tordai, Itoh-san, Geoff Stone, Kirill Sokolovsky's
team and Kyoto U. team have reported the observations.
     This object faded from the second "rebrightening-superoutburst" and turned
back to 14.7 mag last night. This brightness is about 0.5 mag brighter than that
before this superoutburst. Although the light curve shows superhump-like
modulations, the period is unclear due to short visibility (about one cycle).
     Thus, world-wide observations are strongly encouraged to detect the
modulations and determine the period.
