July 22, 2009, bright aurora suddenly and surprisingly glowed
in the Northern latitudes because NOAA explains, “a crack opened in Earth's
magnetic field, allowing solar wind to pour in and fuel the storm. Northern Lights
descended as far south as the Dakotas, Montana, Iowa and Wisconsin. The solar wind is still blowing, but the crack has closed, bringing an end to the aurora lights.”
Who knows
Later
