Overview
HSC 569 is a poorly populated, loose object of low C3 quality. Its parallax locates it at a very close distance, above the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.
Note: This object shares a moderate percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
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.
