Space WeatherDuring space weather events, geomagnetic field variations produce geoelectric fields (GEFs) that drive geomagnetically induced currents (GIC), which may affect operation of power systems, pipelines, railway signaling, and submarine cables.

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Satellite observations during ionospheric modification experiments have reported trans‐ionospheric high‐frequency (HF) wave propagation even when the pump frequency lies below the peak plasma frequency. Such behavior is often attributed to large‐scale density irregularities that locally permit ordinary‐mode (O‐mode) propagation, but this does ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

UHV AC/DC power grid geomagnetically induced currents harmonic characteristics analysis
International Journal of Electrical Power & Energy SystemsThe power grid’s geomagnetically induced currents (GIC) during geomagnetic storms, are associated with a broad and abrupt harmonic impact, with the potential for grid paralysis and extensive power outages in severe scenarios.

Space weather and UK geomagnetically induced currents [PDF]
, 2004 Geomagnetically Induced Currents (GIC), which can flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms.

Why Do Sudden Commencements Sometimes Generate Disproportionate Geomagnetically Induced Currents?
Space WeatherGeomagnetically 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.
