Colorful Northern Aurora (1)

Aurora is a bend in the sky to the extension of folding, it seems will be the flow of light, usually in the high latitudes of North and South latitude (especially the north and south latitude 67 degrees clitellum scope), easier to see, so called Aurora. In the Arctic near the Northern Lights are called, who called in the Antarctic near the southern lights. Eskimo population "Aurora " which means "goddess of the Department of Light." 

 High latitudes of the Earth's upper atmosphere in the luminous phenomenon is the solar wind interaction with the Earth's magnetic field results. Scientists are of the view that: The electric solar wind particles collision with the Earth's magnetic field, guided by the Earth's magnetic field, the flow of the magnetic South Pole and the magnetic North Pole, from the ground in about 80 ~ 120 kilometers around, and the atmosphere of the gas molecules (especially nitrogen and oxygen) in collision of these air molecules are excited and luminous. 

 Aurora gorgeous, absolutely wonderful. This is because in the upper atmosphere contains different elements of the gas, which after the collision by the light. Usually the most common to see the Northern Lights is the green and yellow is the result of the section with energy particle collisions from the ground only 40 miles generated by oxygen molecules; when nitrogen molecules by particle collisions, will issue a red light; ionizing of nitrogen will issue a Blu-ray; and nitrogen and will issue a red light. Therefore, people can see red, blue, green, purple and white light covered the sky. Beautiful aurora also showed changes in the shape of infinity, a curtain-like, flared, ribbon and a variety of shapes, such as ray-like. 

 The strength of the solar wind and the sun's surface by the impact of the activities, the more active when the sun surface, the more sunspots or flares erupted, or coronal holes bigger issued to the stronger solar wind, the charged particles containing more; when the Shares in the more densely near the solar wind through the Earth, it will cause relatively Behind the Aurora, people can see even more spectacular than usual in the Aurora scene, or the lower-latitude regions will also appear Aurora. If by the end of October 2003 to early November, the sun's surface for several X-class Super flash flame and the phenomenon of coronal mass eruption, making even the latitude of the United States several times, only 40 Florida Buddha can see Aurora. 

 The emergence of Aurora need to have two conditions, first, the temperature must be low, and the other is better weather. There are a number of world countries will often Northern Lights, including Norway, Russia, Finland, Scotland, northern Canada and Alaska and other places, of which Finland is where Santa Claus Village. And Canada's Alberta Fort (Ft. McMurray) and Yukon province Whitehorse City In addition to relatively inexpensive price, the Aurora is the best viewing, the time for the annual October to April the following year.
