TL;DR: For example, NASA's magnetospheric multiscale (MMS) mission has found direct evidence for electron demagnetization and acceleration at sites along the sunward boundary of Earth's magnetosphere where the interplanetary magnetic field reconnects with the terrestrial magnetic field as discussed by the authors.

TL;DR: The Radiation Belt Storm Probes (RBSP)-Energetic Particle, Composition, and Thermal Plasma (ECT) suite contains an innovative complement of particle instruments to ensure the highest quality measurements ever made in the inner magnetosphere and radiation belts as mentioned in this paper.
Journal ArticleDOI
High-resolution sounding rocket observations of large-amplitude Alfven waves
TL;DR: Shear Alfven waves with amplitudes greater than 100 mV/m were observed on two recent sounding rocket flights as mentioned in this paper, showing a downward propagation direction and implying insignificant reflection from the ionosphere at frequencies greater than 1 Hz.
Journal ArticleDOI
On low‐altitude particle acceleration and intense electric fields and their relationship to black aurora
TL;DR: In this article, a comparison of these characteristics to those of the black aurora point at a symmetry between the aurora and the electric field, the polar regions being associated with negative divergence of the electric fields and the black regions with positive divergence.
