Summary

FoF 939 is a moderately populated, very loose object of low C3 quality. It is located at a moderate distance from the Sun, near the mid-plane. It is rarely studied 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=0.78) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
