The electrons that create auroras start in the outer layers of the field, where it is compressed by the solar wind. They accelerate along the field lines, converging toward the magnetic poles from all directions. This results in an oval ring around each magnetic pole where auroras occur.
Rings around the Poles. The electrons that create auroras start in the outer layers of the field, where it is compressed by the solar wind. They accelerate along the field lines, converging toward the magnetic poles from all directions. This results in an oval ring around each magnetic pole where auroras occur. The north pole aurora is called the aurora borealis and the aurora at the south pole is called the aurora australis.  In the atmosphere Auroras usually occur in the ionosphere (the highest part of the atmosphere, between the thermosphere and the exosphere. The ionosphere gets its name because it is ionized by solar radiation.). We typically see auroras only in high-latitude areas above about 50 degrees (north or south). The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermos … phere, the outermost actual atmosphere. Aurora Australis (The Southern Lights) can be seen in the Southern Hemisphere (the southern parts of Australia, New Zealand, South America, South Africa and Antarctica). The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermos … phere, the outermost actual atmosphere. The auroras, both surrounding the north magnetic pole (aurora borealis) and south magnetic pole (aurora australis) occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere. Solar winds stream away from the sun at speeds of about 1 million miles per hour. ­The aurora borealis (the Northern Lights) and the aurora australis (the Southern Lights) have always fascinated mankind, and people even travel thousands of miles just to see the brilliant light shows in the earth's atmosphere. The auroras generally occur along the auroral ovals, which center on the magnetic poles (not the geographic poles) and roughly correspond with the Arctic and Antarctic circles. There are times, though, when the lights are farther south, usually when there are a lot of sunspots. ­The aurora borealis (the Northern Lights) and the aurora australis (the Southern Lights) have always fascinated mankind, and people even travel thousands of miles just to see the brilliant light shows in the earth's atmosphere. Images of the aurora australis and aurora borealis from around the world, including those with rarer red and blue lights. An aurora is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions. Auroras result from emissions of photons in the Earth's upper atmosphere, above 80 km (50 mi), from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based molecules returning from an excited state to ground state. It begins with a solar flare. The aurora borealis (northern lights) form when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere.  It is visible from high southern latitudes in Antarctica, South America, New Zealand, and Australia. Auroras also occur on other planets. Similar to the Earth's aurora, they are also visible close to the planets’ magnetic poles. Auroras result from emissions of photons in the Earth's upper atmosphere, above 80 km (50 mi), from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based molecules returning from an excited state to ground state. The aurora borealis and aurora australis occur in the Ionosphere from around 100 km up. This layer of the atmosphere is also called the Thermosphere. 53 people found this useful.
