Discrete aurora are structured into distinctive features with effectively-outlined edges such as arcs, rays and coronas; Additionally they are typically Significantly brighter when compared to the diffuse aurora.
Crimson: At its greatest altitudes, psyched atomic oxygen emits at 630 nm (crimson); very low focus of atoms and reduce sensitivity of eyes at this wavelength make this colour obvious only below much more intensive photo voltaic action.
This phenomenon is called an aurora. The northern lights tend to be more formally known as the aurora borealis mainly because borealis means north in Latin. The southern lights, In the meantime, are called the aurora australis.

If the final course of movement immediately after scattering is near to the field line (especially, if it falls in the loss cone) then the electron will hit the atmosphere.
