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

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective
Space Weather, Volume 24, Issue 1, January 2026.Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.

Geomagnetically induced currents in a Norwegian transformer station [PDF]
, 2022 This report considers measurements of geomagnetically induced current (GIC) and comparison to recorded variations in the geomagnetic field (dB/dt). The GIC-sensors were installed in the neutral point of a 420 kV transformer located in Mid-Norway in 2019.

Space Weather, Volume 24, Issue 1, January 2026.Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...

Investigating Geomagnetic Disturbances in the Expansion Phase of Strong Substorms
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract This study contributes to improved space weather forecasting by investigating geomagnetic disturbances (GMDs) associated with rapid decreases in the SuperMAG Auroral Electrojet Lower (SML) index during strong substorms (SML < ${< } $ −500 nT) at high latitudes (64° ${}^{\circ}$–75° ${}^{\circ}$ MLAT).
