SDSS J170213.26+322954.1 : refined ephemeris 

 We have received further observations from Gianluca Masi.
According to these data, two eclipses were obtained. Using these
eclipses, the refined eclipse ephemeris is the following;

E(BJDmin) = 2455766.0764 (4) + 0.100081 (10) 

 As to the profile of superhumps, small variations like QPO are
seen. Such variations are not unusual in the later stage
of superoutburst, however, those of this object seem frequent.

 Further observations are encouraged!
