Overview

ℹ️

UBC 1280 is a rich, very dense object of low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is poorly studied in the literature.

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