On Sunday, February 8, 2026, a significant increase in solar activity is expected on Earth, leading to the occurrence of a powerful magnetic storm. The relevant forecast regarding solar and geomagnetic activity was released by the Space Weather Prediction Center of the National Oceanic and Atmospheric Administration (NOAA) of the United States.

Geomagnetic Activity Forecast for February 7-8
Geomagnetic storms are classified according to the K-index level, which ranges from 2 to 9. The higher the K-index, the stronger the storm and its effects on people, electronics, and communication systems. On Saturday, February 7, a moderate level of solar activity is expected with a K-index of 4 (yellow level), which will lead to minor magnetic disturbances that remain virtually unnoticed by most people.
However, on Sunday, February 8, an increase in solar activity is forecasted, provoking a magnetic storm with a K-index of 5 (red level). This storm is estimated to last only until the end of the day, after which the intensity will decrease.
Changes in Forecasts and Impact on Health
Experts emphasize that solar activity forecasts are updated every three hours, so changes in the schedule and intensity of magnetic storms are possible. As astronomers note, the most accurate forecasts are those made one day prior to the events, while more distant estimates are approximate.
Geomagnetic storms are classified by their power level – the K-index – ranging from 2 to 9. The higher the K-index, the stronger the storm and its consequences and impact on people and technology.
Magnetic storms can affect people’s well-being, especially those who are sensitive to weather changes, and can also cause temporary disruptions in the operation of technical devices and energy systems.
