The best time to see the ligths is winter or early spring
the ultimate energysource of the aurora is the solar wind flowing past the earth
the auroras, occur when highly charged electrons from the solar wind interact with elements inthe earth's atmosphere. solar winds stream away from the sun at speeds of about 1 million miles per hour. when they reach the earth, some 40 hours afterleaving the sun, they follow the lines of magnetic force and flow through the magnetosphere
¬ the color of the aurora depends on which atom is struck, and thealtitude of the meeting.
some people call this phenomenon the "dance of the spirits."
there are many stories aboutsounds associated with auroras, but there are no recordings of auroral sounds. scientists can't agree on what would produce sounds during the aurora
inorder to get full value from the show you should avoid the full moon and places with a lot of light as they make the experience considerably paler.
bothjupiter and saturn have magnetic fields much stronger than earth's, auroras have been observed on both, uranus and neptune have also been observed to have auroras.
