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

Characterization of Regional Space Weather Conditions in Mexico During Solar Minimum 24/25: Baseline for Severity Scale Development

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Using observations from the National Space Weather Laboratory's (LANCE acronym in Spanish) ground‐based network, we characterize regional space weather conditions in Mexico during the solar minimum 24/25 (2018–2020). Data analyzed include regional geomagnetic indices (the regional K index, Kmex, and Δ ${\Delta }$H), ionospheric Total Electron ...

Geomagnetic observatories: monitoring the Earth’s magnetic and space weather environment [PDF]

, 2014
Geomagnetism research provides insight into the Earth’s properties and processes, from the core out to space. For this reason continuous geomagnetic field observations have been carried out in the UK for more than 170 years. Geomagnetism also has diverse

Why Do Sudden Commencements Sometimes Generate Disproportionate Geomagnetically Induced Currents?

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Geomagnetically Induced Currents (GICs) in grounded, conducting infrastructure (e.g., power networks) represent an important space weather hazard. GICs are driven by the changing magnetic field at the Earth's surface. Due to a sparsity of GIC measurements, the rate of change of the horizontal geomagnetic field H′ $\left({H}^{\prime }\right ...

Topology Control Analysis Mitigations for Geomagnetically Induced Currents [PDF]

, 2016
Geomagnetic disturbances (GMD) are caused by corona mass ejections (CMEs) from the sun. These solar CMEs cause changes in the earths magnetic field, which in turn produce non-uniform electric fields.

Mid‐Latitude Geoelectric Field Response in North China During the May 2024 Superstorm: Effects of Geological Heterogeneity

Space Weather, Volume 23, Issue 9, September 2025.
Abstract Geoelectric field disturbances during geomagnetic storms pose growing risks to mid‐latitude power systems, yet direct observations remain limited. We report multi‐station, real‐time GIE observations from a new monitoring network in North China, comprising 22 geoelectric and 4 geomagnetic stations.

Strong Westward Current Pulse at Auroral Latitudes Extending to Dawn‐Side Low‐Latitudes Due To Enhanced Density Within Kelvin‐Helmholtz Wave Vortex in Solar Wind

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract A series of coronal mass ejections (CMEs) from the Sun, interacted with one another and formed a complex interplanetary‐CME (ICME) that impinged Earth's magnetosphere on 10 May 2024 and caused the strongest geomagnetic storm of the past two decades.
