Overview
HSC 2506 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, young cluster (see Parameters). It was recently reported in the literature.
Note: This is very likely a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.
