Sunspot 5395, source of the March 1989 solar storm. From “A 21st Century View of the March 1989 Magnetic Storm” by D. Boteler.
"It was the biggest geomagnetic storm of the Space Age," says Dr. David Boteler, head of the Space Weather Group at Natural Resources Canada. "March 1989 has become the archetypal disturbance for understanding how solar activity can cause blackouts."
It seems hard to believe now, but in 1989 few people realized solar storms could bring down power grids. The warning bells had been ringing for more than a century, though. In Sept. 1859, a similar CME hit Earth's magnetic field-the infamous "Carrington Event"- sparking a storm twice as strong as March 1989. Electrical currents surged through Victorian-era telegraph wires, in some cases causing sparks and setting telegraph offices on fire. These were the same kind of currents that would bring down Hydro-Québec.














Comment: Preparation like the above is all well and good for 'once in a hundred year events' but our planet appears to be entering a grand solar minimum that is producing effects throughout our solar system unlike our civilization has ever known:
- Cosmic climate change: 'Space plasma hurricane' observed in ionosphere above North Pole!

- Gulf Stream System at its weakest in over a millennium, last significant decline recorded during the little ice age
