Overview

ℹ️

HSC 713 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a large distance, above 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 object shares a moderate percentage of members with a later reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
