Overview
HSC 2555 is a sparse, very loose object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by very high extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It was recently reported in the literature.
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.
