Aurora occurs in earth’s upper atmosphere, mostly in high latitudes of both hemispheres. High-speed particles ejected from the Sun ionise the molecules of air and results in spectacular colour display which can be described by columns of rapidly shifting patches of light of different hues. If you have chance it is wonderful to see this phenomenon but some side effects can be interference to radio signals, telephone, satellite, and disturbances in terrestrial magnetism. The length of maximum and minimum intensity of an aurora is affected by the sunspot cycle, usually at its opposite. Aurora’s ability to assume infinite forms only makes it more magnificent. Such are the aurora arch, an aurora band, aurora clouds, aurora glow. Here are some great pictures of various aurora lights taken around the world.
