Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading

Space Weather, Volume 24, Issue 6, June 2026.
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Dynamics of High‐Latitude Energy Conversion in the Upper Thermosphere Based on 9‐Year Measurements From FPI and Dynasonde in Tromsø, Norway

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract This study highlights the need to re‐evaluate energy transfer in the upper thermosphere at high latitudes through analysis of 9‐year measurements of neutral wind (u) from a Fabry‐Perot interferometer and ion velocity (v) from a Dynasonde in Tromsø, Norway.

Solar Wind–Magnetosphere–Ionosphere Coupling Under Extreme External Driving: Characteristics of Dayside Ground Magnetic Disturbances

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The objective of the present study is to investigate solar wind‐magnetosphere‐ionosphere coupling (SWMIC) under intense external driving in terms of dayside ground magnetic disturbances. Dayside magnetic reconnection drives a region‐1 sense current system, the SWMIC current system.

A study of Sq(H) variations over equatorial electrojet regions

, 2007
The newly established geomagnetic field observations in Japan, have enabled us to analyse the 1998 data of Huancayo, Kiritimati (Christmas Island) and Pohnpei where the geomagnetic Sq(H) variations of equatorial electrojet have been studied. The diurnal

Variations of geomagnetic H, D, and Z field intensities on quiet days at west african latitudes

Moldavian Journal of the Physical Sciences, 2009
In the framework of the French participation to the International Equatorial Electrojet Year (IEEY), a network of ten electro-magnetic stations was installed at African latitudes. These stations measured digitally the three components of the magnetic

Geoelectric Field Caused by Flux Transfer Events in an Ionosphere‐Coupled Vlasiator Simulation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We report on the relationship between flux transfer events (FTEs) at Earth's magnetopause and the geoelectric field that is induced near the FTEs' magnetic footpoints. We study this system using the global hybrid‐Vlasov code Vlasiator, which has recently been extended to model ionospheric physics.
