Analysis of Long‐Term GIC Measurements in Transformers in Austria

Space Weather, 2022
Geomagnetically induced currents (GICs), a result of solar wind interaction with the Earth's magnetic field and the resistive ground, are known to flow in power transmission grids, where they can lead to transformer damage and grid operation problems. In

Linking Very Near‐Earth Reconnection (VNERX) to Mid‐Latitude GICs: Evidence From the 7 September 2017 Storm

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.

Mapping a Carrington Storm

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract A map is presented of median 1‐min‐resolution peak geoelectric‐field strength across the United States as would be induced by magnetic storms as intense as the 2 September 1859 Carrington storm. The map is constructed from two data sets: Magnetometer time series from 22 ground‐based observatories recording 40 magnetic storms, and surface ...

Geomagnetically Induced Current Modeling in New Zealand: Extreme Storm Analysis Using Multiple Disturbance Scenarios and Industry Provided Hazard Magnitudes

Space Weather, 2022
Geomagnetically induced currents (GICs) are induced in electrical power transmission networks during geomagnetic disturbances. Understanding the magnitude and duration of the GIC expected during worst‐case extreme storm scenarios is vital to estimate ...

Statistical Modeling and Prediction of Ionospheric Equivalent Currents Based on SuperMAG Data

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We present a Solar Wind driven SuperMAG statistical Equivalent Current model (SW‐SMEC), which represents the ionospheric equivalent currents in the Northern Hemisphere. The model is based on average current patterns derived from SuperMAG ground magnetometer data covering the solar cycle 23 (1997–2008).

The First Three‐Dimensional Electrical Resistivity Model of the Lithosphere Beneath Britain

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Magnetotelluric data provide unique information to study the electrical resistivity of the Earth's lithosphere, enabling studies of geological structures, tectonic processes, resource exploration, and hazard monitoring. Here, we present the first fully three‐dimensional (3D) electrical resistivity model of the deep lithosphere beneath Britain (
