The Northern Lights additionally coloured the Italian sky pink in a really uncommon phenomenon, as a result of a powerful geomagnetic storm. This can be a uncommon phenomenon as a result of the auroras are seen virtually solely within the polar areas, the place the interplay between the Earth’s magnetic subject and the swarm of particles coming from the Solar is extra intense.

This occurred as a result of over the course of two days the Earth’s magnetic subject underwent sturdy stress, as a result of interplay with a swarm of particles (coronal mass ejection, Cme) which occurred on Saturday 4 November, which was adopted on 5 November a brand new Cme extra intense than the primary, observes physicist Mauro Messerotti, professor of Area Meteorology on the College of Trieste. “This resulted in a G3-class sturdy geomagnetic storm,” on a scale starting from G1 to G5. The geomagnetic storm, continues Messerotti, “lasted for a lot of hours and “the auroral oval, the area of interplay of photo voltaic energetic particles with atoms and molecules of the Earth’s environment, expanded to incorporate latitudes as little as 30 levels North” .
