Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation
Recently, Stephens et al. (2023), https://doi.org/10.1029/2022ja031066 utilized a data mining (DM) algorithm, applied to 26 years of magnetospheric magnetometer observations coupled with a flexible formulation of the magnetospheric magnetic field, to ...

Collisionless reconnection in Jupiter's magnetotail

Geophysical Research Letters, 1991
We present the first quantitative study of collisionless reconnection in Jupiter's magnetotail. Recently it has been shown that collisionless reconnection can occur in the Earth's magnetotail quasi‐neutral sheet when the electrons are subject to chaotic pitch angle diffusion.

Compression of Mercury's Dayside Magnetopause to the Surface: A Three‐Dimensional Model of Magnetospheric Structure and Dynamics

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We apply a hybrid model (kinetic ions, fluid electrons) to provide context for MErcury Surface Space ENvironment, GEochemistry, and Ranging (MESSENGER) observations of Disappearing Dayside Magnetosphere (DDM) events at Mercury. Such events have been observed on four occasions and are caused by Coronal Mass Ejections completely removing the ...

Early Solar Wind and Dynamo Magnetic Field Topology Predictions for (16) Psyche and Other Asteroids

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche is a metal‐rich body that might record an ancient coherent magnetization if some relict crust or mantle is preserved. Herein, we use magnetohydrodynamic simulations to predict (16) Psyche's field topology for several distinct pathways: (i) an early solar wind‐induced magnetization imparted after a larger body was impacted,

IMF B y influence on fast earthward convection flows in the near-lunar magnetotail

Geoscience Letters
This study investigates the effects of non-zero IMF B y on the magnetotail B y and fast earthward ion convection (V ⊥ > 200 km/s, "⊥" indicates perpendicular to the magnetic field) in the near-lunar magnetotail plasma sheet using the plasma parameters ...

Relative Contributions of Solar Wind Dynamic Pressure and Interplanetary Electric Field on the Early Positive Part of Main Phase of Geomagnetic Storms

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The important early declining part of the main phase (MP) of geomagnetic storms in SYM‐H (and Dst) from positive main phase onset (MPO) to 0‐level of SYM‐H was somehow missed in the treatment of the storms. We included the missed part (or revised the storms) by raising the 0‐level of SYM‐H to MPO‐level, and showed that the inclusion is ...

Convection in the magnetotail

Eos, Transactions American Geophysical Union, 1991
It is well known that the Earth's magnetosphere is permeated by a large‐scale electric field, E, which in its turn produces a global flow pattern known as magnetospheric convection, with velocity u = (E × B)/B2 . Convection is the key to understanding the global features of the magnetosphere, for instance the large‐scale flow of electric currents along

10 May 2024 Gannon Storm: Connecting Energy Flux With Field Aligned Currents and Cross Polar Cap Potential

Space Weather, Volume 24, Issue 3, March 2026.
Abstract A simulation of the 10 May 2024 geomagnetic storm is used to investigate the theory of cross polar cap potential (CPCP) saturation in Earth's magnetosphere‐ionosphere system. THEMIS B (ARTEMIS P1) satellite magnetic field and plasma measurements at lunar distance upstream in the solar wind drives the Space Weather Modeling Framework (SWMF) in ...

New Soliton Applications in Earth's Magnetotail Plasma at Critical Densities

Frontiers in Physics, 2020
New plasma wave solutions of the modified Kadomtsev Petviashvili (MKP) equation are presented. These solutions are written in terms of some elementary functions, including trigonometric, rational, hyperbolic, periodic, and explosive functions.

Empirical Results on the Magnetic Prandtl Number in the Slow Solar Wind Based on In Situ Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The magnetic Prandtl number in the slow solar wind is estimated by using magnetic and velocity Reynolds numbers. The Prandtl number quantifies the ratio of kinetic to magnetic diffusion rates in a plasma, and indicates which process dominates the transport dynamics in a fluid.
