FSR 1640
(MWSC 2089)
Summary
FSR 1640 is a sparse, very loose object of very low C3 quality. It is located at a moderate distance from the Sun, well below the mid-plane. It is poorly studied in the literature, with no articles listed in the last 6 years.
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.
