Overview
OC 0015 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-poor, very young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is poorly studied in the literature.
