Ionosphere of Near northern hemisphere polar regions
The auroras that are experienced near the polar regions occur because of the strength of the earth's magnetic field. The magnetic field is not very strong at the equator.
They occur the northern atmospheres. Closer to the magnetic poles where the solar storms hit the earth the hardest.
Auroras have no definite size. They occur when charged particles from the Sun ionize particles in the upper atmosphere as they spiral in toward Earth's magnetic field. Auroras may be localized in one area, or may extend from horizon to horizon in the sky.
