Overview
OCSN 41 is a rich, moderately dense object of very high C3 quality. Its parallax locates it at a very close distance, near the mid-plane. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It was recently reported in the literature.
