Overview
UBC 1103 is a rich, moderately dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is poorly studied in the literature.
Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.
