The aurora is caused by the interaction of high-energy particles (usually electrons) with neutral atoms in earth's upper atmosphere. This process is similar to the discharge in a neon lamp, or the fluorescence of a television screen. The strongest auroras are quite bright, comparable to moonlight. The aurora occurs only above altitudes of 80 km, and infrequently above 500 km. The average altitude for a normal intensity aurora is between 110 and 200 km.
Auroras are caused by solar flares from the sun splashing off the magnetic fields of Earth.
particles from the solar wind that are trapped in the earths magnetic field
An Aurora Australis or an Aurora Borealis occurs when streams of particles from the sun's solar winds hit the earth's atmosphere at an angle (as can only happen at the poles). These particles interact with the edges of the earth's magnetic field and when they collide with the gases in the ionosphere, the particles glow creating curtains of blue, green and magenta. An aurora is sometimes accompanied by a crackling sound.

What is the glowing region in the atmosphere called?
the glowing region in the atmosphere is called an aurora. An aurora example of an aurora would be aurora borealis or the northern lights, or the aurora australis which is also known as the southern lights. *<=D
What is the Aurora called in the south?
Aurora Australis or 'Southern lights'.
What causes the Aurora borealis to end?
The sun
What from the sun causes the aurora borealis?
Solar Winds
What causes the Aurora borealis (Northern lights)?
Aurora Borealis is caused by particles hitting earth's atmosphere thermosphere and they are stopped, so they give of their energy in the "Northern Lights" or Aurora Borealis.

What is it called when particles from the sun strike atoms in the ionosphere near the poles?
The described activity causes the generation of the Aurora Borealis and the Aurora Australis.
