The NSF Daniel K. Inouye Solar Telescope presents its first map of the solar coronal magnetic field signals as measured using the Zeeman Effect. The Zeeman Effect polarizes the coronal emission, which requires the advancements of the Inouye to measure as its signals are only a few parts per billion of the Sun’s surface brightness.
