Description

​Continuous vector magnetic-field measurements by the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) allowed us to run data-driven simulations of solar eruptions and perform statistical studies of magnetic-fields for many flares. In this talk I will review new aspects of flare magnetism discovered using SDO data, including progress in data-driven simulations and statistical studies of magnetic-reconnection fluxes, their rates, magnetic fluxes of flare dimmings, and magnetic-field changes during flares. I will summarize how these results, along with statistical studies of coronal mass ejections (CMEs), have improved our understanding of flares and the flare/CME feedback relationship. Finally, I will highlight future directions to improve the current state of understanding of solar-flare magnetism using observations and simulations.
