Overview
HSC 2474 is a sparse, very loose object of low C3 quality. Its parallax locates it at a very large* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a massive, old cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~11.68 kpc) differs significantly from the median photometric distance (~8.97 kpc).
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
