Overview

ℹ️

CWNU 378 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by low extinction. It is catalogued as a metal-rich, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

Note: This object shares a moderate percentage of members with at least one entry reported in the same catalogue. 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.
