Overview
HSC 743 is a sparse, very loose object of high C3 quality. Its parallax locates it at a very close* distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~0.50 kpc) differs significantly from the median photometric distance (~0.99 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.
