“It was the biggest geomagnetic storm in recorded history. The Sun hurled billions of tons of electrons and protons whizzing toward Earth, and when those particles slammed into the planet’s magnetic field they created spectacular auroras of red, green and purple in the night skies — along with powerful currents of electricity that flowed out of the ground into the wires, overloading the circuits. Scientists say it is impossible to predict when the next monster solar storm will erupt and whether Earth will lie in its path. What they do know is that with more sunspots come more storms, and this fall the Sun is set to reach the crest of its 11-year sunspot cycle.”
