A G1 class geomagnetic storm was produced in the early morning hours of December 28, when the suns magnetic field near earth shifted south. This created a crack in the Earth's magnetosphere, allowing energy in the form of solar wind from the sun to flood in and create aurora in the northern hemisphere.

Cameras aboard DMSP satellite F18 produced this picture of the aurora borealis north of Scandinavia this evening.

Cool!
