Summary

HSC 2315 is a poorly populated, very loose object of low C3 quality. It is located at a moderate distance from the Sun, below the mid-plane. It was recently reported in the literature.

This object shares a significant percentage of members with a later reported entry.

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