L’aurora boreale è tipica in particolare delle regioni vicine al Polo Nord, ma qualche volta accade di vederla anche in Svizzera. È stato il caso nella notte fra domenica e lunedì, quando una videocamera posta sul Säntis ha immortalato lo spettacolo fra le nuvole, attorno alle 01.50.
Lo rende noto MeteoSvizzera, pubblicando anche un’immagine su X. L’ultima volta che l’aurora boreale era stata osservata nella Confederazione risaliva al 5 novembre del 2023, precisa l’Ufficio federale di meteorologia e climatologia. Il fenomeno è il frutto dell’interazione fra particelle cariche di origine solare e la ionosfera terrestre.
