OT_J184228.1+483742 : vary weak eralyhumps?

 We have received further observations from Gianluca Masi.
And we also took observations of this object. The newest
data shows variations like superhumps had appeared although
the amplitude was still very small (0.04 mag).
Using PDM analysis, 0.0708 (5) d was obtained. However, since
the curve was rather symmetry and weak secondary peaks were
seen, this may be still earlyhumps. If this variations are
really ordinary superhumps, the inclination of this system
is very small.

 Further observations are encouraged!
