NOAA forecasts moderate geomagnetic storm for October 11

The Space Weather Prediction Center has issued a G2 (Moderate) geomagnetic storm watch for October 11, 2026. This alert is due to two coronal mass ejections (CMEs) from the Sun on October 7 and 8, which are expected to merge before reaching Earth. Such storms can cause minor disruptions to power grids and satellite operations, and may produce auroras visible at higher latitudes.
