Evolution of lunar wake potentials: structure, energy conversion, and their imprints on velocity distributions
Xin An, Vassilis Angelopoulos, Jasper S. Halekas +4
We study the evolution of electric potentials in the lunar wake. The wake potential exhibits two distinct spatial scales. The macroscopic scale arises from solar wind expansion int…
Whistler-mode waves in near-equatorial THEMIS measurements: reconstruction of magnetic field spectra from electric field and plasma measurements
Declan Frawley, Dmitri L. Vainchtein, Anton V. Artemyev +1
Electromagnetic whistler-mode waves are a natural emission in the outer radiation belt and the Earth's magnetotail. The resonant interaction of these waves and energetic electrons…
First Observation of Multiple Very-Near-Earth Reconnection Events During a Single Storm Main Phase
Fekireselassie Beyene, Vassilis Angelopoulos, Christine Gabrielse +11
For the first time, this paper presents three very-near-Earth reconnection (VNERX) events observed within the same 12-hour-long storm main phase. The THEMIS inner probes observed t…
Parker Solar Probe Observations of Compound Reconnection Exhaust Boundaries and Mirror-Mode Structures in the Near-Sun Heliospheric Current Sheet
Weijie Sun, Tai Phan, Jia Huang +12
Magnetic reconnection is a fundamental physical process that can drive rapid conversion of magnetic energy into plasma bulk flows, thermal heating, and particle acceleration in spa…
Properties of the Stormtime Plasma Sheet at the Lunar Distance
A. Runov, V. Angelopoulos, A. V. Artemyev +1
The electron fluxes at energies 100\,keV are shown to be vanishing in the quiet time plasma sheet at geocentric distance of 60 Earth's radii (R) where the Moon traverses th…
Solar Energetic Particle Reflection by Precursor ICMEs: Multi-spacecraft Observations of Bi-Directional Electron Beams at 1 AU
Lucas Liuzzo, Wenwen Wei, Andrew R. Poppe +2
We present case studies of two impulsive solar energetic electron (SEE) events during which particles at energies from 1-600 keV were detected by THEMIS-ARTEMIS orbiting the Moon,…
