Call and Response: A Time-Resolved Study of Chromospheric Evaporation in a Large Solar Flare
Sean G. Sellers, Ryan O. Milligan, R. T. James McAteer
We studied an X1.6 solar flare produced by NOAA AR 12602 on 2014 October 22. The entirety of this event was covered by RHESSI, IRIS, and Hinode/EIS, allowing analysis of the chromo…
The Slowly Varying Corona: I --- Daily Differential Emission Measure Distributions Derived from EVE Spectra
Samuel J. Schonfeld, Stephen M. White, Rachel A. Hock-Mysliwiec +1
Daily differential emission measure (DEM) distributions of the solar corona are derived from spectra obtained by the Extreme-ultraviolet Variability Experiment (EVE) over a 4-year…
On the non-Kolmogorov nature of flare-productive solar active regions
Revati S. Mandage, R. T. James McAteer
A magnetic power spectral analysis is performed on 53 solar active regions, observed from August 2011 to July 2012. Magnetic field data obtained from the Helioseismic and Magnetic…
Prediction of Solar Flare Size and Time-to-Flare Using Support Vector Machine Regression
Laura E. Boucheron, Amani Al-Ghraibah, R. T. James McAteer
We study the prediction of solar flare size and time-to-flare using 38 features describing magnetic complexity of the photospheric magnetic field. This work uses support vector reg…
Complex Flare Dynamics Initiated by a Filament-Filament Interaction
Chunming Zhu, Rui Liu, David Alexander +2
We report on an eruption involving a relatively rare filament-filament interaction on 2013 June 21, observed by SDO and STEREO-B. The two filaments were separated in height with a…
Frozen-in Fractals All Around: Inferring the Large Scale Effects of Small-Scale Magnetic Structure
R. T. James McAteer
The large-scale structure of the magnetic field in the solar corona provides the energy to power large-scale solar eruptive events. Our physical understanding of this structure, an…
Qualities of Sequential Chromospheric Brightenings Observed in Optical and UV Images
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +1
Chromospheric flare ribbons observed in H-alpha appear well-organized when first examined: ribbons impulsively brighten, morphologically evolve, and exponentially decay back to pre…
Coronal Fourier power spectra: implications for coronal seismology and coronal heating
Jack Ireland, R. T. James McAteer, Andrew R. Inglis
The dynamics of regions of the solar corona are investigated using Atmospheric Imaging Assembly (AIA) 171Å and 193Å data. The coronal emission from the quiet Sun, coronal loop foot…
On the sensitivity of the GOES flare classification to properties of the electron beam in the thick target model
Jeffrey Reep, Stephen Bradshaw, R. T. James McAteer
The collisional thick target model, wherein a large number of electrons are accelerated down a flaring loop, can be used to explain many observed properties of solar flares. In thi…
Coronal Mass Ejection Mass, Energy, and Force Estimates Using STEREO
Eoin P. Carley, R. T. James McAteer, Peter T. Gallagher
Understanding coronal mass ejection (CME) energetics and dynamics has been a long-standing problem, and although previous observational estimates have been made, such studies have…
Sequential Chomospheric Brightening: An Automated Approach to Extracting Physics from Ephemeral Brightening
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +2
We make a comparison between small scale chromospheric brightenings and energy release processes through examining the temporal evolution of sequential chromospheric brightenings (…
Toward Reliable Benchmarking of Solar Flare Forecasting Methods
D. Shaun Bloomfield, Paul A. Higgins, R. T. James McAteer +1
Solar flares occur in complex sunspot groups, but it remains unclear how the probability of producing a flare of a given magnitude relates to the characteristics of the sunspot gro…
Automated Solar Feature Detection for Space Weather Applications
David Pérez-Suárez, Paul A. Higgins, D. Shaun Bloomfield +4
The solar surface and atmosphere are highly dynamic plasma environments, which evolve over a wide range of temporal and spatial scales. Large-scale eruptions, such as coronal mass…
Deceleration and Dispersion of Large-scale Coronal Bright Fronts
David M. Long, Peter T. Gallagher, R. T. James McAteer +1
One of the most dramatic manifestations of solar activity are large-scale coronal bright fronts (CBFs) observed in extreme ultraviolet (EUV) images of the solar atmosphere. To date…
Solar Magnetic Feature Detection and Tracking for Space Weather Monitoring
