Overview
OC 0446 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
