UBC 609
Summary
UBC 609 is a sparse, very loose object of low C3 quality. It is located at a moderate distance from the Sun, above the mid-plane. It is poorly 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: contains less than 25 stars with P>0.5 estimated.
Warning: the low UTI value and no obvious signs of duplication (C_dup=0.84) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
