TCPJ18154219+3515598: sign of fading?

     Tamas Tordai, Ian Miller, Crimean Astrophys. Obs. team, Alexandra
Zubareva, Okayama Astrophys. Obs. team, Pavol A. Dubovsky and
Kyoto U. team have reported further obsrevations.

     The typical interval of the rebrightenings was 5 days, but the latest
one was 9 days. Besides, according to our data in August, the brightness
in each dip phase is slightly fading (from 16.0 to 16.2). These may be
a sign of the end of the rebrightening phase.
     In some objects, we can see the change of the superhump period
in the final stage of the rebrightening phase. Further observations
are strongly encouraged to detect the color and superhump period.
