Abstract:
    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. B-V diagrams indicate that
    UKS 2 is an open cluster with age comparable to that of the Hyades. It
    has a reddening of E(B-V)=0.40 and is located at a distance from the
    Sun of d☉≃7kpc. The cluster is located outside the solar radius
    at galactocentric distance projected on the plane rGC≃11kpc, and a
    height z≃-370pc.
