Unusual Enhancement in He(23S) Airglow Brightness Associated With Interplanetary Magnetic Field Northward Turnings During the 2025 New Year's Day Storm

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

Enhancement of Magnetic Flux Transferred to the Magnetotail Due to a Storm‐Time Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Advancements in the study of collisionless magnetic reconnection and plasma waves

地球与行星物理论评
Magnetic reconnection and plasma waves share a critical connection. On the one hand, quasi-steady wave structures (shock, KAW eigenmode) play a pivotal role in the formation and structure of magnetic reconnection.

A Machine Learning‐Based Model of Three‐Dimensional Ion Fluxes in the High‐Altitude Earth's Northern Cusp

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Magnetic reconnection at the dayside magnetopause is the primary pathway for transferring mass, momentum, and energy from the solar wind into the terrestrial magnetosphere. Previous studies have shown that the spatiotemporal dynamics of dayside magnetic reconnection can be inferred remotely from properties of Earth's cusps, specifically their ...

Magnetic reconnection in flux-tubes undergoing spinning footpoint motions [PDF]

, 2007
Aims.Photospheric motions acting on the coronal magnetic field have the potential to build up huge amounts of magnetic energy. The energy may be released through magnetic reconnection, and so a detailed understanding of the 3D process is crucial if its ...

Interplay between magnetic reconnection and turbulence

, 2023
Shay, Michael A.Reconnection and turbulence frequently occur in plasmas, including laboratory, astrophysical and space plasmas. Over the past few decades, the interrelationship between turbulence and magnetic reconnection has been the focus of increasing

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 ...

Flare energy release by flux pile-up magnetic reconnection in a turbulent current sheet [PDF]

, 2000
The power output of flux pile-up magnetic reconnection is known to be determined by the total hydromagnetic pressure outside the current sheet. The maximum energy-release rate is reached for optimized solutions that balance the maximum dynamic and ...

Current Sheet Geometry and Heavy Ion Influence on Reconnection

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In some planetary magnetospheres singly ionized heavy ion species can be found in addition to the typical hydrogen. The presence of these ions can affect many magnetospheric processes. The role heavy ions, specifically oxygen, and the thickness of the current sheet play in magnetic reconnection is investigated using particle‐in‐cell ...
