An Observational Overview of Solar Flares (2011, background): “…distinct regions (e.g., Cui et al. 2006; Barnes & Leka 2006), and the “effective connected magnetic field” (Georgoulis & Rust2007) – shows promise, as do estimators of the global non-potentiality of the magnetic field such as the flux-normalized field twist (e.g., Falconer et al. 2002).”
Driving major solar flares and eruptions: A review (2008, background): “The findings by Falconer et al. (2006) (expanding on Falconer et al., 2002, 2003) suggest a more complex dependency: for a sample of active regions with one well-defined, dominant polarity-inversion line they find that several measures are correlated similarly to the region’s flare potential.”
Quantitative Forecasting of Major Solar Flares (2007, background): “Falconer et al. (2002, 2003, 2006) attempted to predict CMEs from various nonpotentiality indices of the source ARs, but they have yet to show statistically significant results.”
The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: SHARPs – Space-Weather HMI Active Region Patches (2014, methodology): “A variety of methods have been proposed (Pevtsov, Canfield, and Metcalf, 1995; Leka et al., 1996; Leka and Skumanich, 1999; Falconer, Moore, and Gary, 2002) based on fits to differences from a linear force-free field, moments of the distribution of α, and taking ratios of spatial averages…”
WHY IS THE GREAT SOLAR ACTIVE REGION 12192 FLARE-RICH BUT CME-POOR? (2015, background): “Statistical studies have shown good correlation between CME occurrence and magnetic twist, electric current, and global free energy proxies (Falconer et al. 2002, 2006).”
A COMPARISON OF FLARE FORECASTING METHODS. I. RESULTS FROM THE “ALL-CLEAR” WORKSHOP (2016, methodology): “Falconer et al. (2008) presented a prediction method based on parameterizing active region magnetic morphology that was first applied to CME prediction (Falconer et al. 2002, 2003) but more recently extended to flares.”
Nonlinear Force-free Field Modeling of a Solar Active Region around the Time of a Major Flare and Coronal Mass Ejection (2007, background): “…the displacement of preexisting magnetic flux by plasma flows on the surface (e.g., Leka et al. 1996; Wheatland 2000; Démoulin et al. 2002b, 2002a; Falconer et al. 2002; Leka & Barnes 2003a, 2003b; Schrijver et al. 2005; Wiegelmann et al. 2005; Régnier & Canfield 2006; Jing et al. 2006;…”
