Northern lights

My digital doodle of the northern lights. A couple of days ago the sun threw off a medium sized Coronal Mass Ejection (CME). A plume of hot plasma which the Sun throws out every few days into space. This time it was a halo CME which was pointing directly at us on Earth.

The Sun releases plasma and radiation which can cause effects like auroras on Earth. Streams of electrons and ionised gas travel down the magnetic lines of force that surround the Earth in a protective layer. They hit out atmosphere and glow different colours depending on what atoms they excite.

Yesterday aurora were seen quite far down the longitude of the Northern hemisphere. It might happen again tonight. The sky glowed. I don’t live far enough north to be able to see it. One day I hope I do.

Most of this is written from memory after reading about the Northern lights. If you want more information please check out relevant websites like spaceweather.com
