The Photospheric Imprints of Coronal Electric Currents. I. Magnetic Structure near Polarity Inversion Lines

Abstract Flares and coronal mass ejections (CMEs) are powered by magnetic energy stored in coronal electric currents. Here, we use photospheric vector magnetic field observations to study currents in active regions 10930 and 11158, which both produced eruptive, X-class flares. We...
