Overview

ℹ️

OCSN 46 is a rich, very dense object of very high C3 quality. Its parallax locates it at a very close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a metal-rich, intermediate-age cluster (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is very likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~0.44 kpc) differs significantly from the median photometric distance (~0.79 kpc).
