Polar auroras, aka North-South pole rays were recorded by cameras at International Space Station which is situated 350 kilometers away from the earth.
Meteorologically, an aurora, especially seen in the sky in poles, is the result of charged particles colliding, creating bright lights in the sky. Polar lights, appearing in green usually, can be sighted in blue and purple colors as well.
More often observed during night, the luminescence is mainly formed in ionosphere and seen frequently among north and south 60th thru 72nd degree latitudes.
