MASTER_OT_J072948.66+593824.4: negative superhumps?

   An analysis of the data yielded apparent two strong periodicities
0.06237(3) d, dominating signal, and 0.06436(4) d.
The waveform of the former resembles those of negative superhumps
in ER UMa.  The former period is 3.1% shorter than the latter period.
If the second period corresponds to the orbital period, we may be
witnessing negative superhumps as the main signal!
(There may be some indication of a period of 0.0665 d -- positive
superhumps?).
   Further observations (as well as in future quiescence) are
naturally most strongly desired!
