Overview

ℹ️

CWNU 2013 is a sparse, loose object of low C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a young cluster (see Parameters). It was recently reported in the literature.

Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.

⚠️ 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.
