NotesAn open star cluster on the southern fringes of Monoceros, C54 shows a loose structure, with its more massive members tending to cluster within its distinct core, while less massive stars form a more diffuse halo around the cluster. The denser core region represents approximately one third of the cluster's full diameter.
