Dana,
I opened
http://vizier.u-strasbg.fr/viz-bin/VizieR then put "2mass,ucac4" in the "find catalogs", "10 40 18 -59 49 12.5" in the "target", set the radius to 20 arcsec and clicked Go.
It gave me 9 objects in 2MASS and 5 in UCAC4. With a few more steps you can add NOMAD, but it seems to just return the same objects as 2MASS.
I have UCAC4 and NOMAD catalogs for CdC. These are the closest hits:
4UC 10h40m52.60s -59°53'30.6" * UCAC4-151-055463 mV:14.97 b-v: 0.72 pmRA: 14 [mas/y] pmDE: -24 [mas/y] flags: 0
nmd 10h40m52.66s -59°53'32.2" * nmd 0301-0207604 mV:13.08 mB: mR: pmRA: 16 [mas/y] pmDE: -42 [mas/y] date: 1968.30 Jmag:13.941 Hmag:13.692 Kmag:13.71
Those will be JNOW.
