Awesome it truly is . Wonder what makes it happen and why it's almost always in the north ?
This phenomenon happens when plasma particles borne by the solar wind interact with the earth's upper atmosphere. It happens in both the Northern and Southern polar regions.
@Happyheretic What kind of plasma?
@MrTallman
The solar wind brings a gas made up of free electrions and positive ions. This is known as solar plasma.
@Happyheretic Thanks
