Overview

ℹ️

HSC 6 is a sparse, 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 young cluster (see Parameters). It was recently reported in the literature.

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.68) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
