Polar dawn

Polar dawn if revealing in some colors.

The Polar Dawn is an optic and luminous phenomenon that occurs in the neighborhoods of the polar zones through energized particles comings of the Sun. Such composed particles for prótons and electrons exceed the magnetic lines of the planet and when entering in contact with the atmospheric gases they provoke the luminous effect that can be in form of spot, thin, arc, band or veil and still different colors as green, red, violet and blue. The gases that in contact with such particles promote such effect are the oxygen and the nitrogen.

As cited previously, the polar dawn occurs next to the polar zones. Boreal dawn is the name given to the phenomenon when this occurs in the hemisphere north while Austral Dawn is the name given to the phenomenon when this occurs in the south hemisphere. Such phenomena can occur in such a way in the summer how much in the winter, however hardly it is seen during the summer, therefore it becomes invisible the light of the day in this period. Better they are seen in periods of September - October and in February - March.

The dawns are not particularitities of the Land, therefore as it is a external phenomenon can come to occur in other next planets to the Sun as Venus, Mars, Saturn and Jupiter.
