Overview

â„šī¸
HSC 606 is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a very close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It was recently reported in the literature.

âš 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.
