Tonny Vanmunster, Tamás Tordai, Jesse Leahy-McGregor,
Kirill Sokolovsky, Stephen M. Brincat, Charles Galdies,
Alexandra Zubareva, and Vihorlat Observatory team have
reported further observations.

TCP J21040470+4631129 shows a special superoutburst
that was triggered by the third rebrightening on 25th
Aug (cf. vsnet-alert 23511).

The light curve profile for this 2nd superoutburst looks like
the ordinary SU UMa-type superoutburst.

According to my O-C analysis, superhumps of this
superoutburst might show stage A-B transition on 28th Aug.

Time-resolved observations are encouraged.
