Overview

ℹ️

CWNU 4227 is a sparse, loose object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by very high extinction. It is catalogued as a young cluster (see Parameters). It was recently reported in the literature.

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