Flare Productivity of Major Flaring Solar Active Regions: A Time-series Study of Photospheric Magnetic Properties
Eo-Jin Lee, Sung-Hong Park, Yong-Jae Moon
A solar active region (AR) that produces at least one M- or X-class major flare tends to produce multiple flares during its passage across the solar disk. It will be interesting if…
Magnetohydrodynamic Modeling of a Solar Eruption Associated with X9.3 Flare Observed in Active Region 12673
Satoshi Inoue, Daikou Shiota, Yumi Bamba +1
On SOL2017-09-06 solar active region 12673 produced an X9.3 flare which is regarded as largest to occur in solar cycle 24. In this work we have preformed a magnetohydrodynamic (MHD…
Photospheric Shear Flows in Solar Active Regions and Their Relation to Flare Occurrence
Sung-Hong Park, Jordan A. Guerra, Peter T. Gallagher +2
Solar active regions (ARs) that produce major flares typically exhibit strong plasma shear flows around photospheric magnetic polarity inversion lines (MPILs). It is therefore impo…
Testing and Improving a Set of Morphological Predictors of Flaring Activity
Ioannis Kontogiannis, Manolis K. Georgoulis, Sung-Hong Park +1
Efficient prediction of solar flares relies on parameters that quantify the eruptive capability of solar active regions. Several such quantitative predictors have been proposed in…
Connecting Coronal Mass Ejections to their Solar Active Region Sources: Combining Results from the HELCATS and FLARECAST Projects
Sophie A. Murray, Jordan A. Guerra, Pietro Zucca +5
Coronal mass ejections (CMEs) and other solar eruptive phenomena can be physically linked by combining data from a multitude of ground-based and space-based instruments alongside m…
