SDSS J075233.17+294339.7: CV?

   Slow secular variation (18.2-20.8) in CRTS.

Nearby object in Gaia (M_V=+9), which suggests a luminosity
of a dwarf nova in quiescence.

075233.170 +294339.54 (2000.0) Gaia_DR2_875941782403757056 plx=1.348(0.222) dismod=9.4 pmra=-1.932(0.350) pmdec=-14.587(0.205) G=18.541 BP=18.509 RP=18.222

NUV=19.251(0.058) FUV=19.195(0.139)

   The overall variation looks too smooth for a dwarf nova
in quiescence, and the SDSS u-g is too blue.
This object would require further study.
