The Evolution of Parallel Electric Field Across the Earth's Magnetosheath

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract In Earth's collisionless magnetosheath, turbulence evolution and energy transformation across the system, especially at kinetic scales, remain poorly quantified without full‐coverage of high‐resolution observations. Using multi‐traversal observations from the 2023 and 2024 Magnetospheric Multiscale (MMS) Unbiased Magnetosheath Campaign, we ...

Locating Heating Channels of the Solar Corona in a Plage Region with the Aid of High-resolution 10830 Å Filtergrams

The Astrophysical Journal
In this paper, with a set of high-resolution He i 10830 Å filtergrams, we select an area in a plage, very likely an extreme-ultraviolet (EUV) moss area, as an interface layer to follow the clues of coronal heating channels down to the photosphere.

Dominance of Bursty over Steady Heating of the 4–8 MK Coronal Plasma in a Solar Active Region: Quantification Using Maps of Minimum, Maximum, and Average Brightness

The Astrophysical Journal, 2022
A challenge in characterizing active region (AR) coronal heating is in separating transient (bursty) loop heating from the diffuse background (steady) heating.

Dust Plumes Induced by a Time‐Varying Electron Beam

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We present laboratory results to address dust charging and lofting on the Moon and other airless planetary bodies in response to time‐varying solar wind and ultraviolet (UV) exposure. In these experiments, dust is exposed to an electron beam that varies in beam energy between 40 and 260 eV as a function of time.

Equatorial F‐Region Responses to the Main Phase of the 10 May 2024 Geomagnetic Storm Over the South American Sector: Observations and Model Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study examines the equatorial ionospheric response over the South American sector during the onset of the extreme 2024 Mother's Day geomagnetic storm, which began at ∼17 UT on 10 May and reached the G5 level. Pronounced disturbances in ionospheric electrodynamics were observed under both daytime and nighttime conditions. Variations in the

Global Three‐Dimensional Simulation of Magnetospheric Dynamics During the Extreme Geomagnetic Storm of 10–11 May 2024

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...
