Overview

ℹ️

UBC 278 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 6 years.

⚠️ Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.
