Cluster observations of bounday layer structure and a flux transfer event near the cusp [PDF]

Annales Geophysicae, 2005
On the 25th January 2002 between 10:00 and 12:00 UT, the four Cluster spacecraft passed through the northern high-latitude cusp, the dayside magnetosphere and into the magnetosheath in a linear formation.

Honeycomb‐Like Magnetosheath Structure Formed by Jets: Three‐Dimensional Global Hybrid Simulations

Geophysical Research Letters
Magnetosheath jets with enhanced dynamic pressure are common in the Earth's magnetosheath. They can impact the magnetopause, causing deformation of the magnetopause. Here we investigate the 3‐D structure of magnetosheath jets using a realistic‐scale, 3‐D

Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

Electron Dynamics in Magnetosheath Mirror‐Mode Structures [PDF]

Journal of Geophysical Research: Space Physics, 2018
AbstractMirror‐mode structures are widely observed in space plasma environments. Although plasma features within the structures have been extensively investigated in theoretical models and numerical simulations, relatively few observational studies have been made, due to a lack of high‐cadence measurements of particle distributions in previous space ...

Multipoint Observations of a SLAMS Evolution and Its Merger With Whistler Waves

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We report multipoint observations of a merger between a Short Large‐Amplitude Magnetic Structure (SLAMS) and 1‐Hz whistler wave packets upstream of Earth's quasi‐parallel bow shock. Using high‐resolution data from the Magnetospheric Multiscale (MMS) mission in a string‐of‐pearls configuration, we track the SLAMS as it evolves, exhibiting ...

Three-dimensional Global Hybrid Simulation of Magnetosheath Jets at Mercury

The Astrophysical Journal Letters
Plasma high-speed jets are common in Earth’s magnetosheath, and they significantly perturb the magnetosheath and affect the magnetosphere. The space environment of Mercury, characterized by the bow shock, magnetosheath, and magnetosphere, shares many ...

THEMIS Observations of Particle Acceleration by a Magnetosheath Jet‐Driven Bow Wave

Geophysical Research Letters, 2019
Localized magnetosheath jets with high dynamic pressure are frequently observed downstream of Earth's bow shock. When such a fast magnetosheath jet compresses the ambient magnetosheath plasma, an earthward compressional bow wave could form.

BepiColombo at Mercury: Three Flybys, Three Magnetospheres

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We examine the first three BepiColombo Mercury flybys Using data from the Miniature Ion Precipitation Analyzer (MIPA), an ion mass analyzer in the Search for Exospheric Refilling and Natural Abundances package on the Mercury Planetary Orbiter designed to study magnetospheric dynamics.

Statistical Estimate of the Magnetopause Reconnection Rate as a Function of the Interplanetary Magnetic Field Clock Angle

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The magnetic reconnection rate at the magnetopause is crucial for solar wind and magnetosphere coupling. However, direct measurement is challenging due to inherent uncertainties and limited electron diffusion region statistics, hindering understanding of the guide field's influence on the normalized reconnection rate.
