Summary

HSC 2142 is a sparse, loose object of low C3 quality. It is located at a relatively 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: contains less than 25 stars with P>0.5 estimated.

Warning: the low UTI value and no obvious signs of duplication (C_dup=0.8) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
