Auroral Phenomena has drawn a great attention from many science fields, physics, chemistry astronomy, etc, and the explanation to such phenomena is incredibly interesting. When the atoms and molecules of the upper atmosphere are stroked by the downward-spiraling energetic particles, the great amount of energy caused by the friction causes the electrons to jump to a higher energy level. When they fall back down to their normal energy level, the energy is expelled in the form of light. The light that is produced in this way is the aurora.

      Solar wind performs a major part, as well, in forming aurora. The solar wind is the supersonic outflow into interplanetary space of plasma from the Sun's corona, the region of the solar atmosphere beginning about 4000 km above the Sun's visible surface and extending several solar radii into space. Solar wind is composed of approximately equal numbers of ions and electrons. The altitude at which auroral emissions are excited depends upon the energy of the precipitating particles and the density of the atmosphere. Aurora changes in shapes, brightness, color, and dynamics, and this variability is dramatically exemplified by the auroral substorm.

      In northern regions like Alaska, the most excellent time to view aurora is around the equinox (March and late September-October) because this time of year offers the best trade-off between mild weather and dark skies. In the summer, skies are dim enough to view aurora, and in midwinter temperatures in the -40 F. degree range make aurora viewing somewhat horrible. The aurora australis is only half of the total aurora, and it can be seen only in the Southern Hemisphere. It is most common in places like Anorectic. And Aurora Borealis only can be seen only in the Northern Hemisphere. The northern light is constantly in motion due to interaction between solar wind and earth's magnetic field.
