The Coronal Global Evolutionary Model: Using HMI Vector Magnetogram and Doppler Data to Model the Buildup of Free Magnetic Energy in the Solar Corona
George H. Fisher, William. P. Abbett, David J. Bercik +11
The most violent space weather events (eruptive solar flares and coronal mass ejections) are driven by the release of free magnetic energy stored in the solar corona. Energy can bu…
Photospheric Electric Fields and Energy Fluxes in the Eruptive Active Region NOAA 11158
Maria D. Kazachenko, George H. Fisher, Brian T. Welsch +2
How much electromagnetic energy crosses the photosphere in evolving solar active regions? With the advent of high-cadence vector magnetic field observations, addressing this fundam…
Sign singularity and flares in solar active region NOAA 11158
Luca Sorriso-Valvo, Gaetano De Vita, Maria D. Kazachenko +8
Solar Active Region NOAA 11158 has hosted a number of strong flares, including one X2.2 event. The complexity of current density and current helicity are studied through cancellati…
