Overview
HSC 2281 is a moderately populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.
Note: This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry. See table with shared members information.
