Photometric measurements of stars in the intermediate-age galactic cluster NGC 6633 are presented. From these data the color excess is found to vary slightly across the cluster with an average of E/sub b-y/ = 0.124m. The distance modulus is found to be 7.71m and the turnoff occurs at about (b--y)$sub 0$ = 0.1m. The cluster is slightly metal poor. (auth)
