The Extreme Space Weather Event of 1872 February: Sunspots, Magnetic Disturbance, and Auroral Displays
Hisashi Hayakawa, Edward W. Cliver, Frédéric Clette +19
We review observations of solar activity, geomagnetic variation, and auroral visibility for the extreme geomagnetic storm on 1872 February 4. The extreme storm (referred to here as…
Temporal Variations of the Three Geomagnetic Field Components at Colaba Observatory around the Carrington Storm in 1859
Hisashi Hayakawa, Heikki Nevanlinna, Séan P. Blake +3
The Carrington storm in 1859 September has been arguably identified as the greatest geomagnetic storm ever recorded. However, its exact magnitude and chronology remain controversia…
Relaxation Based Modeling of GMD Induced Cascading Failures in PowerModelsGMD.jl
Adam Mate, Arthur K. Barnes, Steven K. Morley +3
A major risk of geomagnetic disturbances (GMDs) is cascading failure of electrical grids. The modeling of GMD events and cascading outages in power systems is difficult, both indep…
The Extreme Space Weather Event in February/March 1941
Hisashi Hayakawa, Sean P. Blake, Ankush Bhaskar +3
Given the infrequency of extreme geomagnetic storms, it is significant to note the concentration of three extreme geomagnetic storms in 1941, whose intensities ranked fourth, twelf…
A Detailed Model of the Irish High Voltage Power Network for Simulating GICs
Seán P. Blake, Peter T. Gallagher, Joan Campanyà +5
Constructing a power network model for geomagnetically induced current (GIC) calculations requires information on the DC resistances of elements within a network. This information…
Geomagnetically Induced Currents in the Irish Power Network during Geomagnetic Storms
Seán P. Blake, Peter T. Gallagher, Alan G. Jones +6
Geomagnetically induced currents (GICs) are a well-known terrestrial space weather hazard. They occur in power transmission networks and are known to have adverse effects in both h…
