An unusual display of nocturnal lights, the polar aurora, appeared in Italy, a very rare event for our latitudes.
During the late afternoon, with peak visibility from 18:00 to 19:00, the sky was colored with shades of red and violet above the peaks of the Alps and on various elevations in the north, extending even to the southern region of Puglia.
Previously, a similar display occurred in Italy on September 25, when a polar aurora covered the skies of Lombardy and South Tyrol in red.
This celestial display, known in the northern hemisphere as the aurora borealis, consists of a luminous show during which dynamic chromatic stripes of red, green, and blue are observed in the Earth’s atmosphere, generated by the interaction between particles carried by solar winds and the Earth’s atmosphere. Generally, due to the particular geographical position of our planet, they can be predominantly observed in northern European countries, such as the Scandinavian countries and Iceland.
The unusual sight of this aurora was caused by a violent solar disturbance that hit our planet.The event is the result of a G3 category solar storm, on a scale where the maximum is G5, so intense that within the Arctic Circle the phenomenon was even perceived during the day, in the presence of sunlight, a fact that occurs rarely, almost once every decade.
