M. Mierla, A. N. Zhukov, D. Berghmans +24
We report observations of a unique, large prominence eruption that was observed in the He II 304 Å passband of the the Extreme Ultraviolet Imager/Full Sun Imager telescope aboard S…
Solar Flare Effects on the Earth's Lower Ionosphere
Laura A. Hayes, Oscar S. D. O'Hara, Sophie A. Murray +1
Solar flares significantly impact the conditions of the Earth's ionosphere. In particular, the sudden increase in X-ray flux during a flare penetrates down to the lowest-lying D-re…
Quasi-Periodic Particle Acceleration in a Solar Flare
Brendan P. Clarke, Laura A. Hayes, Peter T. Gallagher +2
A common feature of electromagnetic emission from solar flares is the presence of intensity pulsations that vary as a function of time. Known as quasi-periodic pulsations (QPPs), t…
