(4) The most common colors of light are red, pale greenish-yellow bluish-purple light blue and pink. (5) These light bands are actually created by collisions between gaseous particles in the earth's atmosphere and charged solar particles from the sun's atmosphere. (6) Since the temperature above the surface of the sun is extremely hot, collisions between gas molecules are very frequent. (7) The variety of color are due to the different gas particles that come together. (8) The pale greenish-yellow color comes from oxygen particles colliding 60 miles above the atmosphere of the earth. (9) The purplish-red color comes from nitrogen particles colliding at a height of 200 miles above the earth's atmosphere.
(10) Researchers try to view the lights during the winter season in the North Pole, because the night skies are clear at this time, giving them the opportunity to observe the lights better. (11) In North America the ideal places to watch the lights are the northwestern parts of Canada and Alaska. (12) In the arid, desert-type regions of Antarctica or the south pole, auroras are not seen very often.
(13) During the early mornings, the aurora takes on a cloud-like appearance and then disappears as the sun rises. (14) In the polar regions, the aurora is visible for at least six months in a year. (15) The aurora extends toward the equator when the weather activity in space increases and there are more storms and sub-storms. (16) If the activity in space is intense, the aurora can be seen even from Asia and Europe. (17) However, the sky must be clear and free from clouds to watch this event from so far away.
(18) Many legends and superstitions came to exist because of these lights. (19) During medeival times, people thought that the lights from the aurora brought bad luck. (20) The Maori of New Zealand believed that they were lights from torches.
