Overview

ℹ️

FSR 0371 is a sparse, very loose object of low C3 quality. Its parallax locates it at a very large^* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~10.96 kpc) differs significantly from the median photometric distance (~3.54 kpc).

⚠️ 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.
