Overview
ℹī¸
CWNU 2100 is a sparse, very 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 an intermediate-age cluster (see Parameters). It was recently reported in the literature.

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