Source: adapted from T.S. Molinski, W.E. Feero and B.L. Damsky (2000) “Shielding grids from solar storms”, IEEE Spectrum. The geomagnetic north pole is located approximately at 80 degrees of latitude on Ellesmere Island in Canada. Because of the structure of the earth’s electromagnetic field, a geomagnetic storm creates field disturbances … Continue reading Probability of a Geomagnetic Storm with a Field Change Greater than 300 Nanoteslas per Minute (22-year cycle)
