The Dynamic Response of Jovian Magnetotail Reconnection to Enhanced Solar Wind Ram Pressure

The Astrophysical Journal
In this study, we employ the Grid Agnostic Magnetohydrodynamic (MHD) for Extended Research Applications (GAMERA), a high-resolving-power, three-dimensional global MHD model, to simulate magnetotail reconnection in Jupiter's magnetosphere.

Universal Time Influence on Stormtime Magnetosphere Ionosphere Coupling

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract The offset between Earth's magnetic and rotational axes introduces a diurnal dependence in the high‐latitude EUV exposure of the northern hemisphere (NH) and southern hemisphere (SH). This variation raises the question: Does the Universal Time (UT) of geomagnetic storm onset impact its geospace consequences?

Rapid Response of Martian Magnetotail to Solar Wind Disturbance: Tianwen‐1 and MAVEN Joint Observations

Geophysical Research Letters
The Martian magnetotail is largely controlled by the solar wind (SW) and is modulated by variations in the upstream drivers. However, due to the limitations of single‐spacecraft observations, the effects of SW variations on the Martian magnetotail have ...

Magnetotail magnetic flux monitoring based on simultaneous solar wind and magnetotail observations [PDF]

Journal of Geophysical Research: Space Physics, 2016
AbstractThe magnetotail magnetic flux (MTF) is an important global variable to describe the magnetospheric state and dynamics. Existing methods of MTF estimation on the basis of the polar cap area, inferred from observations of global auroras and field‐aligned currents, do not allow benchmarking due to the absence of a gauge for comparison; besides ...

Finding Local Parallel Electric Fields in Magnetotail Reconnection Using a Two‐Spacecraft Method

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the use of a novel two‐spacecraft Liouville‐mapping method using data from the Magnetospheric Multiscale mission to determine local magnetic‐field‐aligned (parallel) electric fields in the Earth's magnetotail. The method detects the presence of local acceleration potentials by mapping phase‐space density between electron ...

Magnetotail reconnection onset caused by electron kinetics with a strong external driver

Nature Communications, 2020
Magnetotail reconnection plays a crucial role in explosive energy conversion in geospace. Here, the authors show that magnetotail reconnection starts from electron reconnection in the presence of a strong external driver, which then develops into ion ...

Earthward Flow Bursts in the Magnetotail Driven by Solar Wind Pressure Impulse [PDF]

Journal of Astronomy and Space Sciences, 2008
On August 31, 2001, ~ 1705 - 1718 UT, Cluster was located near the midnight magnetotail, GSE (x, y, z) ~ (-19, - 2,2) RE, and observed fast earthward flow bursts in the vicinity of the neutral sheet.

Local Time Asymmetry in Energetic Electron Distribution Within Saturn's Inner Magnetosphere

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electrons of several hundred keV in Saturn's ring current are important seed components of the radiation belt. In this study, we have statistically analyzed the spatial distribution of energetic electrons on the equatorial plane of the inner magnetosphere based on the Cassini in situ observations.

Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H Lyman ⍺ emission from the disk of Uranus observed by HST from 2011 to 2022 are not ...
