We present the first color-magnitude study for Palomar 2, a distant andheavily obscured globular cluster near the Galactic anticenter. Our (V,V-I)color-magnitude diagram (CMD), obtained with the UH8K camera at the CFHT,reaches V(lim) = 24 and clearly shows the principal sequences of the cluster,though with substantial overall foreground absorption and differentialreddening. The CMD morphology shows a well populated red horizontal branch witha sparser extension to the blue, similar to clusters such as NGC 1261, 1851, or6229 with metallicities near [Fe/H] = -1.3$. From an average of severalindicators, we estimate the foreground reddening at E(B-V) = 1.24 +- 0.07 andobtain a true distance modulus (m-M)_0 = 17.1 +- 0.3$, placing it about 34 kpcfrom the Galactic center. We use starcounts of the bright stars to measure thecore radius, half-mass radius, and central concentration of the cluster. Itsintegrated luminosity is M_V = -7.9, making it clearly brighter and moremassive than most other clusters in the outer halo.Comment: 25 pages, aastex, with 8 postscript figures; accepted for publication  in AJ, September 1997.
