The US National Oceanic and Atmospheric Administration has issued a G3 geomagnetic storm warning, with isolated phases possibly reaching G4 level. The northern lights could be visible over northern Germany and the coasts tonight, from June 5 to 6, thanks to minimal cloud cover.
For the best view, look north. Smartphones with night mode and longer exposure capture colors the human eye cannot see in real time.
Solar storms can disrupt navigation systems, satellites, and power grids. In 2022, 40 Starlink satellites burned up in a solar storm. However, such dangerous events remain rare.
