Overview
UBC 1622 is a sparse, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age 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.
