Transcript of Aurora Borealis
What's the Difference?
The lights are seen above the North pole, light seen above the south pole is called the Aurora Australis. Other than being in different poles there is do no difference between the Aurora Australis and the Aurora Borealis.
Where Can you see it?
The Aurora Borealis can be seen from many places such as Finland, Iceland, Norway, Scotland, and Alaska. You can see it best from these places because the phenomenon occurs near the north pole and these places are up north. The farthest south that the Aurora Borealis has been seen was in New Orleans. It is rare to see the Aurora Borealis in the south because the phenomenon occurs near the north pole and the electrons can not spread that far down.
Color an How Its Made
The color of the Aurora Borealis is most commonly a yellowish green this is caused by oxygen molecules located about 60 miles above the earth. All-red auroras are very rare, they are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora.The aurora borealis form when charged particles released from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. These collisions turn into countless little bursts of light, called photons, which make up the Aurora Borealis. The Aurora Borealis is visible from late September to March anywhere from 6pm to 6am. They can last anywhere from a few minutes to all night.
