Overview
UBC 229 is a rich, 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, but with a large variance across recent sources for the absorption and age parameters (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.
