USNO-A2.0 0750-09453854: faint UG? or low luminosity CV?
CRTS 17.2-18.6 (observations around 17.2 look
low-amplitude outbursts).
Nearby object in Gaia (M_V = 12.2)
160811.260 -135058.13 (2000.0) Gaia_DR2_4341529414413909632 plx=4.728(0.292) dismod=6.6 pmra=-0.073(0.634) pmdec=-4.167(0.500) G=18.797 BP=18.716 RP=18.650
GALEX:
NUV=19.268(0.124) FUV=19.975(0.258)
Looks like a low luminosity CV such as a WZ Sge-type object.
If it is indeed a dwarf nova, outbursts can reach mag 10-11.
