Auroras became visible sporadically in the Swiss sky on Thursday evening. They were recorded by various webcams, including the one from Weisshorn Arosa in Graubünden. The spectacle was not visible everywhere due to varying cloud cover.
In the northern hemisphere, auroras are also known as northern lights. Such northern lights are rare in the Alpine region, as the weather service Meteonews writes. They are mainly seen in polar regions.
Auroras occur when electrically charged particles from the solar wind collide with oxygen and nitrogen atoms in the upper layers of the Earth's atmosphere and ionize them. This creates the different colors. The green aurora originates from an altitude of around 100 to 200 kilometers, while the red aurora originates from an altitude of over 200 kilometers.
