Overview

ℹ️

FSR 0319 is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~3.66 kpc) differs significantly from the median photometric distance (~1.68 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.

Relatively close Moderate extinction Intermediate age
