Wils_SDSSJ074859.55+312512.6: eclipsing dwarf nova below the period gap

   Maeda-san has reported time-series observations.
The brightness (16.4 mag) on Nov. 24 was still above
the quiescent level.  There were 0.6-mag eclipses
with a period of 0.058 d.  An analysis with the data
combined with CRTS data yielded the following ephemeris.

Min(BJD) = 2457351.21283(2) + 0.0583110901(7) E

   The object is most likely an eclipsing SU UMa-type
dwarf nova.  The low outburst amplitude is probably
due to the high inclination.
