The forecast of solar and geomagnetic activity for August 9, 2025 was published by the Space Weather Prediction Center of the National Oceanic and Atmospheric Administration of the United States.
Geomagnetic storms are classified by their power level – K-index – from 2 to 9. The higher the K-index, the stronger the storm and its consequences and impact on people and equipment.
On Saturday, August 9, solar activity with a K-index of 5 (red level) is expected, which corresponds to strong magnetic storms.
It is important to note that magnetic storm forecasts are subject to change as solar researchers update their data every three hours. Therefore, we recommend that you monitor the changes regularly.
