Summary

HSC 381 is a poorly populated, very loose object of high C3 quality. It is located at a very close distance from the Sun, above the mid-plane. It was recently reported in the literature.This is a unique object, which shares a very small percentage of members with at least one previously reported entry.

Warning: the low UTI value and no obvious signs of duplication (C_dup=0.96) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
