OT_J184228.1+483742 : early superhumps?

 We have received further observations from Maehara-san, Okayama
Univ. of Sci. team (includeing Akazawa-san),  Gianluca Masi. 
According to these data, that this object shows variations with 
~ 0.05 mag. The period of variations is not clear, however, the
newest data shows the period of 0.0591(4) d. Though this period
is a match for WZ Sge type dwarf nova, shorter periodic variations
 seem to be dominant as far as seeing the light curve. Rather
these variations appear to be QPO.
 The next development attractes attentions. Further observations
are encouraged!
