Data & Observations


The COronal Solar Magnetism Observatory (COSMO) is a unique ground-based facility designed to address current shortfalls in our capability to measure magnetic fields in the solar corona. COSMO comprises three elements. The first two focus on chromospheric and prominence magnetometry (ChroMag), and observing the electron scattered K-corona (K-Cor). The third and central instrument is the 1.5-m aperture Large Coronagraph (LC) that will continuously observe the radiation emitted by the corona in a number of visible and near-IR emission lines.
