Wils_SDSSJ162520.29+120308.7 variation, type?

   Just received data from Gianluca Masi.  Indeed interesting modulations!
The object was rather rapidly fading at a rate of 0.38 mag/d.
Superimposed (relatively regular) modulations have a period of 0.047(8) d,
as Masi has pointed out.  Although this periodicity needs to be verified,
if this period reflects the orbital or superhump period, the object may be
analogous to V485 Cen and EI Psc (then consistent with the underlying
M-type spectrum).  It even seems to me that underlying white dwarf was
visible around Hbeta and Hgamma on the SDSS spectrum.
Further detailed observations are encouraged!
