Overview
CWNU 1397 is a poorly populated, loose object of low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It was recently reported in the literature.
