TL;DR: High-resolution electron observations obtained during the 9 October storm are reported and chorus scattering explains the temporal evolution of both the energy and angular distribution of the observed relativistic electron flux increase, and detailed modelling demonstrates the remarkable efficiency of wave acceleration in the Earth's outer radiation belt.

TL;DR: In this paper, a series of brief, strong (delta p/p = 1), dynamic pressure oscillations that occurred in the region upstream of the earth's bow shock during a period of radial interplanetary magnetic field was analyzed.

TL;DR: In this paper, high altitude measurements of high altitude ions and electrons at auroral energies are used to provide evidence of parallel electric field acceleration over the dusk to midnight auroral regions for both the north and south hemispheres.

TL;DR: In this paper, the authors quantitatively evaluate chorus-driven electron acceleration during the 17 March 2013 storm, when the Van Allen Probes observed very rapid electron acceleration up to several MeV within ~12 hours.

TL;DR: In this paper, the electron-scale plasma measurements revealed super-Alfvenic electron jets reaching 15,000 kilometers per second, electron meandering motion and acceleration by the electric field, producing multiple crescent-shaped structures in the velocity distributions, consistent with fast reconnection.
