TCP J21040470+4631129: stage A superhumps with a very short period?

   The most recent data by Stephen Brincat on July 17-18
suggest superhumps with a period of 0.0519(5) d.
The profile suggests growing stage A superhumps.
If this period is established, the object is well below
the period minimum and should be an unusual one.
Intensive observations (including spectroscopy)
are encouraged.
