A. Warmuth, F. Schuller, R. Gómez-Herrero +39
(abridged) The acceleration of particles at the Sun and their propagation through interplanetary space are key topics in heliophysics. Specifically, solar energetic electrons (SEEs…
Ion-rich acceleration during an eruptive flux rope event in a multiple null-point configuration
Melissa Pesce-Rollins, Alexander MacKinnon, Karl-Ludwig Klein +8
We report on the -ray emission above 100~MeV from the GOES M3.3 flare SOL2012-06-03. The hard X-ray (HXR) and microwave emissions have typical time profiles with a fast rise to…
