The sun is starting to wake up after Solar Minimum. Apparently there was a coronal mass ejection from the sun yesterday. This means that a twisted magnetic line of energy had broken and exploded with plasma coming out of the Sun. The energy can fly out in any direction but sometimes the CME heads towards Earth, then the magnetic feild around the Earth shields us. Except at the poles. Its like when you put iron filings on a bar magnet. You can see the magnetic field lines and the way the iron filings follow them. The magnetic lines dip down towards the magnetic poles. This is what happens at the North and South poles of Earth. The energy from the sun is channelled towards the poles and excites the gasses in the atmosphere. I think Nitrogen glows green and Oxygen pink? I’m not sure.

Anyway there has been a CME from the Sun and the chance is there might be some Auroral displays in the next few days.
