Overview

ℹ️

UBC 371 is a poorly populated, loose object of low 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, very young cluster (see Parameters). It is poorly studied in the literature.

Note: This object shares a moderate percentage of members with 3 later reported entries. See table with shared members information.
