The cause of such a large-scale light phenomenon were two super-powerful flares on the Sun. After them, the streams of magnetic plasma streamed to the Earth, which reached its magnetic field, turned into a magical polar glow. According to scientists, this was also largely promoted by favorable weather conditions.
Polar or northern lights occur in the upper atmosphere. It is characterized by an incredible color variety with a predominance of pale green and pink shades. The presence of nitrogen in the atmosphere “provokes” red, blue and violet colors, and greenish-yellow – caused by collisions of oxygen molecules at altitudes of about 100 km. Red auroras occur much higher – at an altitude of over 320 km.
