Overview
HSC 1108 is a sparse, loose object of intermediate C3 quality. Its parallax locates it at a large* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a very metal-poor, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~6.47 kpc) differs significantly from the median photometric distance (~4.20 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.
