Addressing Known Challenges in Solar Flare Forecasting I: Limb-Flare Prediction with a 4-pi Full-Heliosphere Framework
K. D. Leka, Eric L. Wagner, Lisa Upton +3
A demonstrated failure mode for operational solar flare forecasting is the inability to forecast flares that occur near, or just beyond, the solar limb. To address this shortcoming…
On the Uniqueness and Causal Relationship of Precursor Activity to Solar Energetic Events: I. Transient Brightenings -- Introduction and Overview
Karin Dissauer, Graham Barnes, KD Leka +1
The physical role played by small-scale activity that occurs before the sudden onset of solar energetic events (SEEs, i.e., solar flares and coronal mass ejections) remains in ques…
Properties of Flare-Imminent versus Flare-Quiet Active Regions from the Chromosphere through the Corona II: NonParametric Discriminant Analysis Results from the NWRA Classification Infrastructure (NCI)
KD Leka, Karin Dissauer, Graham Barnes +1
A large sample of active-region-targeted time-series images from the Solar Dynamics Observatory / Atmospheric Imaging Assembly, the AIA Active Region Patch database ("AARPs", Paper…
Properties of Flare-Imminent versus Flare-Quiet Active Regions from the Chromosphere through the Corona I: Introduction of the AIA Active Region Patches (AARPs)
Karin Dissauer, KD Leka, Eric L. Wagner
We begin here a series of papers examining the chromospheric and coronal properties of solar active regions. This first paper describes an extensive dataset of images from the Atmo…
On Identifying and Mitigating Bias in Inferred Measurements for Solar Vector Magnetic Field Data
K. D. Leka, Eric L. Wagner, Ana Belén Griñón-Marín +2
The problem of bias, meaning over- or underestimation, of the component perpendicular to the line-of-sight, Bperp, in vector magnetic field maps is discussed. Previous works on thi…
The NWRA Classification Infrastructure: Description and Extension to the Discriminant Analysis Flare Forecasting System (DAFFS)
K. D. Leka, Graham Barnes, Eric L. Wagner
A classification infrastructure built upon Discriminant Analysis has been developed at NorthWest Research Associates for examining the statistical differences between samples of tw…
Evaluating (and Improving) Estimates of the Solar Radial Magnetic Field Component from Line-of-Sight Magnetograms
K. D. Leka, G. Barnes, E. L. Wagner
Although for many solar physics problems the desirable or meaningful boundary is the radial component of the magnetic field , the most readily available measurement is t…
A Comparison of Flare Forecasting Methods, I: Results from the "All-Clear" Workshop
G. Barnes, K. D. Leka, C. J. Schrijver +15
Solar flares produce radiation which can have an almost immediate effect on the near-Earth environment, making it crucial to forecast flares in order to mitigate their negative eff…
