Solar Storms: Earth Braces for Potential Double Impact and Aurora Sightings

The sun emitted several coronal mass ejections (CMEs) over the weekend, prompting warnings of a potential double solar storm impact on Earth. Predicted to hit on April 16, 2025, and last until April 17, these CMEs could trigger a G2-class geomagnetic storm. This increases the possibility of witnessing auroras, even in regions like Germany. A CME impacted Earth's magnetic field on April 15, 2025, causing G1 to G2-level geomagnetic storms for 12 hours. While the storms subsided, NOAA forecasts a potential resurgence on April 16, especially if another CME arrives, with a G3 (strong) storm warning still in effect. Though long-term solar storm predictions remain impossible, short-term warnings are feasible. The typical delay between a solar eruption and a storm's arrival on Earth is one to two days.
