What is the Northern Light?
The Northern Light phenomenon occurs when solar winds throw electrically charged particles toward the Earth. The particles are electrons and protons which create light when they collide with gases in the atmosphere.
The Northern Light phenomenon depends on the activity at the Sun. Strong activity at the Sun one day may cause powerful Northern Lights three or four days after.
The magic Northern Light
The Northern Light may occur rapidly like a dancing light that sweeps across the sky. And it may disappear as rapidly. It varies in brightness and with several colours from green and yellow to red and orange. The Northern Light has many variations in shapes from circles to spirals and some times you may see it like a vertical curtain with different colours. It can also be like a sort of cloud in the sky.
Myths and superstitions
In older days many people believed that the Norther Light could influence people in general and therefore we should not tease the Northern Light. Brandishing a white cloth or to wistle, then the Northern Light would catch you. Nor should one laugh at the Northern Light because one could become paralyzed. Most people were afraid of the Northern Light, they believed it was a bridge between the Earth and Heaven and that it opened for contact with dead persons.
Today we have knowledge about the Northern Light and we know it's not dangerous and we may enjoy this fantastic colourizing phenomenon lighting up the sky in periodes.
