Joint Analysis With Swarm and Ground Stations: Ionospheric Current System and Geomagnetically Induced Currents

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Sudden changes in the ground magnetic field, driven by geomagnetic activity, can ultimately generate geomagnetically induced currents (GICs), which can have a significant impact on artificial technology systems. High rates of change in the horizontal geomagnetic field (dH/dt) can be used as a substitute for the strength of GICs.

The MANA Magnetometer Array, and Magnetic Observations Across New Zealand From 2024

Space Weather, Volume 24, Issue 2, February 2026.
Abstract This paper describes the Magnetometer Array for New Zealand Aotearoa, or MANA, completed in 2023. The network consists of five new variometer sites to complement the existing Eyrewell geomagnetic observatory. Here, we describe the technical details and capabilities of the network, including the hardware and software used. Data products include

Severe Distortion of the Apparent Resistivity Induced by the Super Geomagnetic Storm in May 2024

Geophysical Research Letters
The potential hazard of geomagnetically induced current (GIC) in metallic pipelines caused by space weather events is a widely discussed topic. On 10–11 May 2024, a super geomagnetic storm with Kp = 9 comparable to the Halloween event in 2003 occurred ...

High‐Precision Prediction of Auroral Substorm Expansion Phase Evolution Using a Spatio‐Temporal Attention Deep Learning Model

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Auroral substorms are a key manifestation of solar‐terrestrial interactions and the release of energy within the Earth's magnetosphere. The expansion phase, which is characterized by rapid changes in auroral morphology and intensity, poses significant space weather risks to satellite operations and communication systems.

Improvement in the modelling of geomagnetically induced currents in Southern Africa [PDF]

, 2016
One of the consequences of the geomagnetic storms resulting from adverse space weather is the induction of geomagnetically induced currents (GICs) in power lines. The GICs that flow in a power transmission network are driven by the induced electric field

The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid

Space Weather, Volume 24, Issue 2, February 2026.
Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.
