Excess of Sodium Ions Density Required to Create a Wide Current at the Hermean Magnetopause

Universe, 2021
In this paper we consider an unusual structure, twice observed at the magnetopause of Mercury, and called the “Double Magnetopause”. Presumably, it is associated with a current sheet created by Na+ ions. Two alternative scenarios are considered.

Coordinated interhemispheric SuperDARN radar observations of the ionospheric response to flux transfer events observed by the cluster spacecraft at the high-latitude magnetopause [PDF]

, 2003
International audienceAt 10:00 UT on 14 February 2001, the quartet of ESA Cluster spacecraft were approaching the Northern Hemisphere high-latitude magnetopause in the post-noon sector on an outbound trajectory.

Statistical analysis of magnetopause crossings at lunar distances [PDF]

Annales Geophysicae, 2019
Different magnetopause models with a diverse level of complexity are in use. One thing that they have in common is that they are mainly based on near-earth observations; i.e.

Global hybrid simulations of soft X-ray emissions in the Earth’s magnetosheath

Earth and Planetary Physics
Earth’s magnetopause is a thin boundary separating the shocked solar wind plasma from the magnetospheric plasmas, and it is also the boundary of the solar wind energy transport to the magnetosphere.

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 ...

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 ...

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 ...

Magnetopause transects

Geophysical Research Letters, 1996
A novel method is described for reconstruction of two‐dimensional current‐layer structures from measurements taken by a single spacecraft traversing the layer. In its present form, the method is applicable only to 2D magneto‐hydrostatic structures that are passively convected past the observing spacecraft. It is tested on a magnetopause crossing of the

Tracing solar wind plasma entry into the magnetosphere using ion-to-electron temperature ratio [PDF]

, 2009
When the solar wind Mach number is low, typically such as in magnetic clouds, the physics of the bow shock leads to a downstream ion-to-electron temperature ratio that can be notably lower than usual.
