Magnetic Storms on September 17–18: Solar Activity Forecast
Increased solar activity is expected on September 17–18. Magnetic storms can affect atmospheric pressure, which may cause some people to experience headaches, fatigue, and stress.
Geomagnetic activity is measured on a scale from 0 to 9. The planetary K-index is used for classification; a reading of 5 or higher indicates a strong magnetic storm.
On Thursday, September 17, solar activity with a K-index of 4.7 (yellow level) is expected, which corresponds to moderate magnetic storms.
On Friday, September 18, solar activity with a K-index of 3.7 (green level) is expected, corresponding to weak magnetic storms.
It is important to note that magnetic storm forecasts may change, as solar activity researchers update their data every three hours. Therefore, we recommend regularly monitoring any changes.
