Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract The significant decrease in the global horizontal geomagnetic field is a key indicator of global magnetic storms and serves as the fundamental basis for deriving traditional disturbance storm‐time indices in space weather monitoring. The disturbance intensity varies across regions and with magnetic local time, highlighting the need for more ...

Methodology for simulation of geomagnetically induced currents in power systems
Journal of Space Weather and Space Climate, 2014 To assess the geomagnetic hazard to power systems it is useful to be able to simulate the geomagnetically induced currents (GIC) that are produced during major geomagnetic disturbances.

Omega Bands as a Source of Large dB/dt in the Dawn Sector
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract Omega band activity has the potential to cause geomagnetically induced currents as they can cause large values of dB/dt $\mathrm{d}B/\mathrm{d}t$. We have undertaken a multi‐instrument study of an omega event which occurred from 13 to 14 November 2012, during a period of southward IMF. Measurements from the European Incoherent SCATter (EISCAT)

Space Weather, Volume 23, Issue 11, November 2025.Abstract Geomagnetically induced currents (GICs) are naturally occurring electrical currents that flow through the Earth and long conductive infrastructure, such as power lines, during geomagnetic storms. GICs in the electric power grid can cause damage to electric power transformers, system failures, and wide‐scale blackouts.

Severe Distortion of the Apparent Resistivity Induced by the Super Geomagnetic Storm in May 2024
Geophysical Research LettersThe 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 ...
