A Probabilistic Framework for Incorporating Helioseismic Far-Side Active Regions into SFT Models
Bibhuti Kumar Jha, Lisa A. Upton, K. D. Leka +5
Surface Flux Transport (SFT) models are routinely used to model the Sun's photospheric magnetic field and provide inner boundary conditions for coronal and heliospheric models, yet…
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…
Learning to Estimate Photospheric Vector Fields from Line-of-Sight Magnetograms
David Fouhey, KD Leka
Solar photospheric line-of-sight magnetograms are easier to estimate than full vector magnetograms since the line-of-sight component (Blos) can be obtained from total intensity and…
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 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…
