Wils_SDSSJ162520.29+120308.7 superhump period

   Enrique de Miguel has reported observations on July 7-8.  The data
show fully developed superhumps with amplitudes of 0.32-0.35 mag.
An analysis of the combined data with Masi's, we have obtained
a mean superhump period of 0.09948(6) d, although an O-C analysis
favors slightly longer (0.0998 d) period.
This confirms Masi's identification of the period, and the object
is a dwarf nova in the period gap.
Since the period of superhumps is expected to be rapidly varying
at this early stage, further observations are absolutely needed
to make a secure determination of the superhump period.
