Aurora phenomenon, a phenomenon that is lighting up the horizon. To north / south. Aurora caused. High-energy particles from the Sun, was released into space in the form of wind, solar (Solar wind) wind blow to Earth at supersonic speeds. Through interplanetary space at speeds ranging from 300 to more than 1000 km / s. When the solar wind collide with Earth's magnetic field. The shape of the outer magnetic field. (Magnetosphere) shaped distortion similar to a comet (Fig. 1) Earth's magnetic field acts like a shield. The protection of high-energy particles from the solar wind and radiation. Most energetic particles can not pass through and turning it around. However, with some being caught in the outer magnetosphere. Then flows along the magnetic field into polar regions with increasing acceleration. Collision with the Earth's atmosphere. Such high energy particles to react with particles in the Earth's atmosphere. These high-energy particles is increased further. Therefore, to maintain the balance of power itself. Need to emit energy in the form of light, some Aurora. As we see. If it happens at the North Pole. We are known as the Northern Lights, or aurora borealis, and if it happens at the South Pole. We are known as auroras, or aurora australis.
Countries with the opportunity to see the aurora often above 60 degrees latitude, so the country would not have a chance to see. Because we are in the latitude is not high enough. (Thailand is located at latitude 5 degrees 37 minutes north and 20 degrees ๋ 27 minutes north).
