Overview
OC 0115 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a close* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the distance and age parameters (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~0.97 kpc) differs significantly from the median photometric distance (~2.30 kpc).
