Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract 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 reconstruct the global configuration of the magnetotail when the Magnetospheric MultiScale ...

Low Frequency Oscillation Observed in the Ionosphere Around the Substorm Onsets

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Three substorm events in which Defense Meteorological Satellite Program (DMSP) spacecraft are geomagnetically co‐located with substorm onset locations in IMAGE far ultraviolet auroral images are analyzed. A Hilbert‐Huang Transform is used to decompose the DMSP B⊥ ${B}_{\perp }$ in the ionosphere to its intrinsic mode functions. A dominant mode

Galactic cosmic rays on extrasolar Earth-like planets I. Cosmic ray flux

, 2015
(abridged abstract) Theoretical arguments indicate that close-in terrestial exoplanets may have weak magnetic fields, especially in the case of planets more massive than Earth (super-Earths).

Magnetosphere

Eos, Transactions American Geophysical Union, 1991
Research on the terrestrial magnetosphere, above 500 km, continues to focus on how energy gets from the solar wind into the magnetosphere and how it circulates through the magnetosphere. The prime candidate for energy coupling has long been magnetic merging in which the magnetic field that the solar wind carries from the Sun merges with the geomagnetic

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 ...

Uncertainties of Modeling Gamma-Ray Pulsar Light Curves with Vacuum Dipole Magnetic Field

, 2010
Current models of pulsar gamma-ray emission use the magnetic field of a rotating dipole in vacuum as a first approximation to the shape of plasma-filled pulsar magnetosphere.

Magnetospheric plasma

Eos, Transactions American Geophysical Union, 1984
The aim of the Chapman Conference on Waves in Magnetospheric Plasmas, February 7–11, 1983, in Hawaii was to bring together investigators of magnetospheric plasma waves having frequencies from VLF whistlers and emissions down through ELF and ULF to Pc5 long period pulsations. The emphasis was on the physics and techniques underlying the entire frequency

Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.

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.

Upward, MeV‐Class Electron Beams Over Jupiter's Main Aurora

Geophysical Research Letters
Jupiter's poleward (Zone II) main aurora exhibits bi‐directional electron acceleration; upward acceleration dominates but downward acceleration generates strong aurora.
