Overview
FSR 0069 is a sparse, very loose object of high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by high extinction. It is catalogued as a very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied 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.
