The aurora borealis, AKA the northern lights are caused by solar activity that triggers magnetic storms.
Solar flares from activity on the surface of the sun and coronal mass ejections release electrically charged particles into space.
The solar wind carries these charged particles from the sun.
And when the particles are captured by the earth's magnetic field they collide with our atmosphere, heating-up the atoms and molecules which release energy in the form of photons, or light particles resulting in the aurora borealis.
And this happens.
From last evening...
