Summary

CWNU 531 is a sparse, very loose object of intermediate C3 quality. It is located at a close distance from the Sun, below the mid-plane. It was recently reported in the literature.

Warning: contains less than 25 stars with P>0.5 estimated.

Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
