When the aurora is no longer visible in the south it appears in the north. The aurora australis is visible during the southern winter, from March to October, while the aurora borealis is visible during the northern winter from the end of September to the end of March. The difference between these two auroras is the place and the period in which they are visible. They occur around the poles of the planet Earth but also of other planets. The aurora australis and the aurora borealis are polar lights. To see northern lights forecast check this website When excited, these atoms emit green, red, pink or violet light. They collide with atoms (hydrogen, oxygen, nitrogen, etc.) in the upper atmosphere (ionosphere), between 80 and 1 000 kilometres above our heads. When the ‘rubber band’ is released, particles are catapulted at high speed towards the Earth along the magnetic field lines that converge towards the Earth’s poles. Behind our planet, on the side opposite the Sun, these deformations stretch the ‘bubble’ like a rubber band. This shield is deformed by the streams of matter expelled by the Sun, like a large soap bubble exposed to the wind. The Earth is surrounded by a magnetic shield (the magnetosphere) that serves as its protection. This is because they are a sign of a disturbance of the Earth’s magnetic field by the solar wind. They are called aurora borealis, but are also sometimes referred to as: aurora borealis, aurora borealis, northern light, northern light, dancing light, northern glow, polar glow, aurora australis in the southern hemisphere, aurora borealis on the net.
