MASTER_OT_J072948.66+593824.4 : the superimposion of two period?

 We have received further observations from Enrique 
de Miguel and William Stein. Fortunately, combined
with Ian Miller's data, these data cover ~ 0.6 day
without blank. These data show that the amplitude of
variations weakened every three peaks. This implies
that multiple periods bring beat phenomenon.
 According to PDM analysis, 0.06357 (17) d and 0.0964 (4)
d were obtained as periods which can able to bring 
beat phenomenon as seen.
 The period implies that this object is likely a 
SU-UMa type dwarf nova. However, such phenomenon is 
not typical in SU UMa-type dwarf nova.

 Further observations are encouraged!
