     No VizieR match, but there are multiple detections in
Pan-STARRS.  The psf-fitted grizy magnitudes are:

g  21.45
r  21.48
i  21.41
z  19.91
y  19.10

(0.05 to 0.1 mag uncertainties)

...so the g,r,i colors are blue, but the z and y magnitudes
toward the far-red indicate a red object, consistent a
cv-like binary system.

     The Pan-STARRS query page is here:
