Colour-magnitude diagrams are presented for the first time, of the faint southern star cluster UKS 2, which was for a long time reported as a globular cluster candidate. The V vs. diagrams indicate that UKS 2 is an open cluster with age comparable to that of the Hyades. It has a reddening of and is located at a distance from the Sun of ≈ 7 kpc. The cluster is located outside the solar radius at galactocentric distance projected on the plane rGC ≈ 11 kpc, and a height pc.
Key words: open clusters: UKS 2 / HR diagram
