Collinder 306
(NGC 6169; MWSC 2424; OCL 984; ESO 276 05; mu Nor)
Summary
Collinder 306 is a sparse, very loose object of very low C3 quality. It is located at a moderate distance from the Sun, above the mid-plane. It is poorly studied 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.
