A Statistical Analysis of the Solar Phenomena Associated with Global EUV Waves
David M. Long, Pearse Murphy, Georgina Graham +2
Solar eruptions are the most spectacular events in our solar system and are associated with many different signatures of energy release including solar flares, coronal mass ejectio…
Measuring the magnetic field of a trans-equatorial loop system using coronal seismology
David M. Long, Gherardo Valori, David Pérez-Suárez +2
"EIT waves" are freely-propagating global pulses in the low corona which are strongly associated with the initial evolution of coronal mass ejections (CMEs). They are thought to be…
Evolution of the Magnetic Field Distribution of Active Regions
Sally Dacie, Pascal Démoulin, Lidia van Driel-Gesztelyi +5
Aims. Although the temporal evolution of active regions (ARs) is relatively well understood, the processes involved continue to be the subject of investigation. We study how the ma…
CorPITA: An Automated Algorithm for the Identification and Analysis of Coronal "EIT Waves"
David M. Long, D. Shaun Bloomfield, Peter T. Gallagher +1
The continuous stream of data available from the Atmospheric Imaging Assembly (AIA) telescopes onboard the Solar Dynamics Observatory (SDO) spacecraft has allowed a deeper understa…
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…
Deriving the Coronal Hole Electron Temperature: Electron Density Dependent Ionization/Recombination Considerations
J. G. Doyle, S. Chapman, P. Bryans +4
Comparison of appropriate theoretical derived line ratios with observational data can yield estimates of a plasma's physical parameters, such as electron density or temperature. Th…
Signatures of Alfven waves in the polar coronal holes as seen by EIS/Hinode
D. Banerjee, D. Perez-Suarez, J. G. Doyle
Context. We diagnose the properties of the plume and interplume regions in a polar coronal hole and the role of waves in the acceleration of the solar wind. Aims. We attempt to det…
