Overview
ℹī¸
Dutra Bica 44 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a very large* distance, above the mid-plane, affected by very high extinction. It is catalogued as an old cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~14.81 kpc) differs significantly from the median photometric distance (~2.26 kpc).

⚠ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
