Impact Plasma Amplification of the Ancient Mercury Magnetic Field

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

MHD simulations of disk-star interaction

, 2008
We discuss a number of topics relevant to disk-magnetosphere interaction and how numerical simulations illuminate them. The topics include: (1) disk-magnetosphere interaction and the problem of disk-locking; (2) the wind problem; (3) structure of the ...

Discovery of nitrogen in Saturn's inner magnetosphere

Geophysical Research Letters, 2005
We detected N+ in Saturn's magnetosphere in the range L ∼ 3.5 to ∼9.5 Saturn Radii (Rs) using data collected by the Cassini Plasma Spectrometer during Saturn Orbit Insertion and the following orbit (Rev A). The presence of N+ in Saturn's magnetosphere has been a source of much debate since Voyager's detection of unresolved mass/charge 14–16 amu ions in

Mercury’s Low‐Latitude Boundary Layer: Identification of Distinct Proton Populations Using MESSENGER Spacecraft Data

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract We have performed a comprehensive analysis of Mercury’s Low‐Latitude Boundary Layer (LLBL) using data from the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) spacecraft during its orbital phase. Using combined magnetic field and ion measurements, we identified 202 LLBL events and categorized them into three distinct ...

GIC‐Related Observations During the May 2024 Geomagnetic Storm in the United States

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The May 2024 geomagnetic storm was one of the most severe in the past 20 years. Understanding how large geomagnetic disturbances (GMDs) impact geomagnetically induced currents (GICs) within electrical power grid networks is key to ensuring their resilience.

Introduction to the thematic series “Coupling of the magnetosphere–ionosphere system”

Geoscience Letters, 2017
This thematic series contains 4 papers mostly presented at the 2016 AOGS meeting in Beijing. The four papers investigate four key regions in the magnetosphere–ionosphere coupling process: mid-tail magnetosphere, near-Earth magnetosphere, inner ...

Control of ULF Wave Accessibility to the Inner Magnetosphere by the Convection of Plasma Density

, 2018
During periods of storm activity and enhanced convection, the plasma density in the afternoon sector of the magnetosphere is highly dynamic due to the development of plasmaspheric drainage plume (PDP) structure.

How Does the Definition of a Geomagnetic Storm Affect the Contents of the Resulting Storm List?

Space Weather, Volume 24, Issue 5, May 2026.
Abstract A geomagnetic storm is a significant and prolonged disturbance of the Earth's magnetic field caused by an enhancement of the ring current. Storms are typically identified using magnetic field measurements from multiple ground‐based magnetometers, and the corresponding dates and times of multiple storms can be collated to form a storm list ...

Predicting CME Arrivals From L5 Heliospheric Imagers: The Impact of HI Track Length

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The Solar TErrestrial RElations Observatory (STEREO) mission has laid a foundation for advancing real‐time space weather forecasting by enabling the evaluation of heliospheric imager (HI) data for predicting coronal mass ejection (CME) arrivals at Earth.
