Magnetic Storms and Solar Activity on September 1–2

On September 1–2, solar activity may cause fluctuations in the Earth’s geomagnetic field. Due to changes in atmospheric pressure, some people may experience headaches, fatigue, and increased exhaustion.

 

Geomagnetic activity is measured on a scale from 0 to 9. The planetary K-index is used to indicate this; a reading of 5 or higher indicates a strong magnetic storm.

On Tuesday, September 1, solar activity with a K-index of 1.7 (green level) is expected, which corresponds to weak magnetic storms.

On Monday, September 2, solar activity with a K-index of 1.7 (green level) is expected, which corresponds to a weak geomagnetic storm.

It is important to note that magnetic storm forecasts are subject to change, as solar activity researchers update their data every three hours. Therefore, we recommend monitoring updates regularly
