Intense, Long‐Duration Geomagnetically Induced Currents (GICs) Caused by Intense Substorm Clusters

Abstract Geomagnetically induced current (GIC) measurements at the Mäntsälä, Finland (57.9° magnetic latitude) gas pipeline from 1999 through 2019 are analyzed. It is found that the GIC events with peak intensity > 10 A are not individual peaks, but occur in clusters with duration from ∼5 to ∼38 ...
