We report CCD UBVRI photometry for the metal-poor cluster NGC 2506, obtained at the WIYN 0.9m at KPNO on February 11, 2006 under photometric conditions. Using Daophot II, spatially-dependent psfs and aperture corrections were applied. Application of color-color diagrams calibrated to the Hyades, the extinction relations of Cardelli et al., and Yale-Yonsei 2002 isochrones yields E(B - V) = 0.09 ± <0.01 ± sys; [Fe/H] = -0.32 ± <0.1 ± sys; (m - M) = 12.95 ± <0.1 ± sys, which results in a distance of 3.421 ± 0.158 kpc ± sys; and an age of 1.79 ± <0.05 Gyr ± sys. This work has been supported by the National Science Foundation under grant AST-0452975.
