Document Summary
In general, 3 conditions are involved in creating aroura: charged particle (from solar wind, magnetic field of the earth (planet, atmosphere of the earth (planet) Solar wind is the continuous outward flow of charged particles (protons and electrons) which are ejected from the sun: these particle can be ejected from the sun"s corona, prominences, or solar flares. Solar prominences, solar flares and coronal mass ejections (cmes) are all possible sources of the solar wind: they are essentially different types of "ejection" of solar material into space. Solar prominence: a solar prominence (also known as filament) is an arc of gas that erupts from the surface of the sun. Prominences can loop hundreds of thousands of miles into space. Prominences are held above the sun"s surface by strong magnetic fields can last for many month. At some time in their existence, most prominences will erupt enormous amounts of solar material into space.
