In the night from Monday to Tuesday you could observe the northern lights over Magdeburg, among other places. According to the American Atmospheric Service NOAA, there was a moderate solar storm overnight. The play of light in the sky is triggered by so-called high-energy solar wind particles, which are thrown into space at high speeds by eruptions on the sun’s surface and hit the Earth’s magnetic field.
There had already been sightings of the northern lights in Germany in April. As a spokesman for the Institute for Solar-Terrestrial Physics at the German Aerospace Center (DLR) announced at the time, the current increase in sightings is not entirely unusual. Approximately every eleven years, in a so-called solar cycle, there are phases with weak and strong solar activity. The next maximum is expected in 2025. Spring and autumn are statistically the best times of year to discover the Northern Lights in Germany.
