   Is there anyone following this target?

   The light curve looks like to me a WZ Sge star
(or less likely, a background nova).  I suspect that the CV
is a fainter (possibly unresolved) companion of the V=14.7
mag star.  NUV=20.8 would be fine for a faint dwarf nova
in quiescence.  If this is indeed a WZ Sge star, the age
may be inconsistent with a G-type star (assuming that they
are physically associated).

   As judged from the light curve, it may be already
superhumping if it is a dwarf nova.  Spectroscopy is also
desired (it was a pity that long rainy season in Japan
prevented observation).
