Summary

HSC 1894 is a poorly populated, loose object of high C3 quality. It is located at a close distance from the Sun, below the mid-plane. It was recently reported in the literature.

This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry.

Warning: the low UTI value and no obvious signs of duplication (C_dup=0.77) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
