The aurora borealis or northern lights are one of nature’s most spectacular phenomena. These beautiful displays of light are caused by the interaction of charged particles from the sun with the Earth’s magnetic field. One of the lesser-known features of the aurora borealis is the auroral line. In this article, we will explore the definition and meaning of the auroral line.
Definitions
The auroral line is a narrow band of light that appears on the horizon during an aurora borealis display. It is caused by the interaction of charged particles with the Earth’s atmosphere. The auroral line is typically green in color, but it can also appear red or blue.
