Overview
FSR 1115 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a close distance, below the mid-plane, affected by very high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
