Overview

ℹ️

CWNU 1187 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a very close distance, above the mid-plane, affected by low extinction. It is catalogued as a young cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: This is very likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.04) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
