Overview
UBC 315 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
Note: This object shares a large percentage of members with 2 later reported entries. See table with shared members information.
