MASTER_OT_J072948.66+593824.4: superhumps?

 We have received further observations Roger Pickard,
Enrique de Miguel, Ian Miller, and Shugarov Sergey.
According to these data, this object showed variations
like superhumps on Feb 21. The decrease of amplitude was
not seen. 
 Meanwhile, the period was not stable. With data reported 
on Feb 22, 0.06648(10) d was obtained. Meanwhile 0.06373(9)
d was obtained on Feb 20. This difference seem too large
if this stems from the difference of stages. Additionally,
clearly period around 0.06 d was not seen on Feb 21 (Though
0.0834(3) d was obtained with PDM method, the light curve
implies that this period was not so reliable.)

 Further observations are encouraged!
