[sixty seven] Though the energy to power the aurora is ultimately derived from the solar wind, the electrons themselves do not vacation straight from the solar wind into Earth's auroral zone; magnetic industry strains from these regions tend not to connect with the photo voltaic wind, so there isn't a immediate entry for photo voltaic wind electrons.

In the case of diffuse auroras, the electron pitch angles are altered by their conversation with several plasma waves. Every single conversation is essentially wave-particle scattering; the electron energy after interacting While using the wave is analogous to its Strength prior to interaction, however the path of movement is altered. If the ultimate route of motion after scattering is near the sector line (especially, if it falls inside the loss cone) then the electron will hit the atmosphere.
Not surprisingly, it wasn’t just the Greeks and Romans who linked the phenomenon Together with the otherworldly. A lot of Inuits understood the aurorae as aqsarniit
