Overview

• NOAA has recorded a significant coronal mass ejection set to strike Earth’s magnetic field and generate a G4 geomagnetic storm on the night of June 1.
• Forecasters at Deutscher Wetterdienst project clear conditions across northwest to central Germany, offering the best aurora viewing opportunities.
• The south and east of Germany are expected to be mostly overcast with showers and thunderstorms, likely blocking aurora visibility there.
• The event occurs during Solar Cycle 25’s peak phase, marked by elevated solar activity and frequent eruptions.
• The G4 storm is less intense than May 2024’s G5 event and could still produce auroras across Europe and parts of the United States along with risks to satellites and power grids.
