TCP J21040470+4631129 : growing superhump?

Tonny Vanmuster and Tamás Tordai have reported their observations on
TCP J21040470+4631129 and we Kyoto University team performed
observations as well.

Most recent observations by Kyoto University show one-peak modulation
with the amplitude of ~0.2 mag and the period of 0.0545(1) d, which
was not detected at the first moments of this rebrightening. (cf.
early superhump period of J2104 : 0.0535 d, stage A superhump period
0.0545 d at the first  superoutburst on July)
This modulation may be a growing superhump, and this rebrightening be
superoutburst!

More follow up observation are encouraged to confirm whether this is a
true superoutburst!
