Four-color and HP photometry has been obtained for 16 stars in the open cluster NGC 6087. Based on this photometry the membership of these stars in the cluster is discussed. Using stars which appear to be members a color excess of E (by) = 0Y23 and a distance modulus of (V, -M,) = 9%0 are derived. This distance modulus is about 0% less than previous values and indicates a lower luminosity for the Cepheid member, S Nor, than is currently accepted.
