Using Photospheric Vector Magnetograms to Drive Coronal Field Models
Abstract
Solar flares and coronal mass ejections (CMEs) are driven by the release of free magnetic energy stored in electric currents in the coronal magnetic field. Without photospheric forcing, the large-scale coronal field should, in principle, maintain a nearly steady equilibrium. Photospheric evolution must therefore play a central role in driving the corona to produce flares and CMEs. Consequently, observations of the photospheric vector magnetic field provide crucial inputs for understanding this
