Crimson aurorae would be the rarest and therefore are due to oxygen at the very best amount of the environment, close to 200 kilometers (124 miles) or more over the Earth’s surface area.
Auroras consequence from emissions of photons in Earth's higher atmosphere, earlier mentioned eighty km (50 mi), from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based mostly molecules returning from an fired up point out to floor state.

These occur from electric currents alongside discipline strains ("area aligned currents"), produced by a dynamo system because of the relative motion involving the rotating planet plus the shifting moon.

The probability of observing the northern lights tonight relies on a number of variables, such as the time of year, the climate and amounts of light pollution.
In the situation of diffuse auroras, the electron pitch angles are altered by their interaction with various plasma waves. Just about every conversation is basically wave-particle scattering; the electron energy just after interacting With all the wave is analogous to its Vitality ahead of conversation, but the route of motion is altered. If the ultimate course of motion after scattering is near the sector line (precisely, if it falls in the loss cone) then the electron will strike the environment.
As Earth's magnetic industry redirects the particles towards the poles the dramatic approach transforms right into a cinematic atmospheric phenomenon that dazzles and fascinates scientists and skywatchers alike. The southern lights, or aurora australis, are made in precisely the same way.
