Overview
HSC 2424 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-poor, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~4.35 kpc) differs significantly from the median photometric distance (~2.93 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.
