SDSS J170213.26+322954.1 : eclipses ephemeris

 We have received observations from Ian Miller.

Conbined with this data, 4 eclipsed have already obseved.
Based these times of eclipses, the ephemeris equation is

E (min) = 2455766.0763 (5) + 0.100092 (19)

 Since the maxima of superhumps were superimposed with the
eclipses, the period of superhump was not clear. However,
considering the previous research, ~ 0.1055 d is supposed.
This period does not deny the profile of superhumps in this
superoutburst.
 Further observations are required!
