FoF 1864
(LP 1864)
Summary
FoF 1864 is a sparse, 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 very 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=0.92) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
