April 2000 geomagnetic storm: ionospheric drivers of large geomagnetically induced currents [PDF]
Annales Geophysicae, 2003 Abstract. Geomagnetically induced currents (GIC) flowing in technological systems on the ground are a direct manifestation of space weather. Due to the proximity of very dynamic ionospheric current systems, GIC are of special interest at high latitudes, where they have been known to cause problems, for example, for normal operation of power ...

Geomagnetically Induced Currents over Kazakhstan during Large Geomagnetic Storms
, 2022 Abstract Extreme solar events, such as flares accompanied by the ejection of a powerful magnetic cloud, cause perturbation of the Earth's magnetic field and form fluctuating currents in the ionosphere and magnetosphere. One of the negative consequences of extreme solar phenomena for technological systems is the appearance of geomagnetically ...

Nuclear Magnetohydrodynamic EMP, Solar Storms, and Substorms
, 2003 In addition to a fast electromagnetic pulse (EMP), a high altitude nuclear burst produces a relatively slow magnetohydrodynarnic EMP (MHD EMP), whose effects are like those from solar storm geomagnetically induced currents (SS GIC).
