Explicit IMF $B_y$-effect maximizes at subauroral latitudes (Dedicated to the memory of Eigil Friis-Christensen)

, 2019
The most important parameter in the coupling between solar wind and geomagnetic activity is the $B_z$-component of the interplanetary magnetic field (IMF).

Geomagnetically Induced Currents, Transformer Harmonics, and Reactive Power Impacts of the Gannon Storm in May 2024

Space Weather
Geomagnetically induced current (GIC) measurements made at two 3 phase, 3 limb transformers, operating in the Halfway Bush substation in Dunedin, New Zealand have been analyzed during the May 2024 Gannon Storm.

Strong geomagnetic disturbances and induced currents on Earth surface [PDF]

, 2008
Long-term variations in strong geomagnetic storms are analyzed and linked to electric fields induced on Earth. In fact, geomagnetic disturbances generate electric fields that drive currents in the Earth which may have significant effects on electrical ...

Measurement of the geomagnetically induced currents (GIC) by the solar activity

, 2019
The aim of this study is to measure the currents geomagnetically induced by the solar activity in the high-voltage powerlines of the electric grid, in order to evaluate when its influence can be a risk to these lines and the electrical supply. The procedure is based on the measurements of magnetic field near the lines.

Instrumentation for monitoring Geomagnetically Induced Currents (GICs)

Geomagnetically Induced Currents (GICs) are the result of rapid variations in the Earth's geomagnetic field, caused by highly energized solar wind, and of the Earth's finite conductivity. These currents flow on the Earth's surface and along grounded conductive infrastructure, such as transmission power networks. In such systems, GICs pose a significant
