The Aurora Borealis

Posted by on Thursday, July 7, 2016

In northern latitudes most people have experienced the aurora borealis (or the northern lights) at some point.
The aurora borealis were named after the Roman goddess of dawn, Aurora, and the Greek name for the north wind, Boreas, by Galileo in 1619.

Auroras seen within the auroral oval may be directly overhead, but from farther away they illuminate the poleward horizon as a greenish glow, or sometimes a faint red.

Auroras are caused by the interaction of the solar wind with the Earth’s magnetosphere. The varying intensity of the solar wind produces effects of different magnitudes.

Approximately 70 meters above the Earth’s surface Aurora noise, similar to a hissing, or crackling noise happens.
