The Northern Lights have always fascinated man and have been a source of inspiration to artists and scientists for decades.
Galileo Galilei was the fist person to coin the phrase ”Aurora Borealis” in the 1600’s.
The Northern Lights occur when electrically charged particles (electrons and protons) come into contact with the magnetic field lines whose footings are in the northern and southern hemisphere.
An understanding of how solar winds affect the Earth’s magnetic field, and how the Northern Lights are formed, is important in order to facilitate better forecasts of solar storms. Improved forecasting makes it easier to protect both satellites that are orbiting the sun and installations on the ground.
So-called solar storms have in several cases knocked out both power supplies and communications for varying periods of time.
