     I note a weak detection in the GALEX near-uv image,
and also on POSS-I blue/red, but much fainter on UK Schmidt
plates.  Assuming the RA end-figures above are 45s.00,
the object seems to correspond to a faint star in the
UKIDSS survey:  17 50 44.96 -25 58 37.2 (J2000) with
J-K = 2.7.  There is a GLIMPSE source 0".26 away at:
17 50 44.94 -25 58 37 (typical scatter ~0".3 in the
Spitzer astrometry).
