In September, the Earth will be surrounded by several strong magnetic storm waves. An increase in geomagnetic activity is expected at the beginning of the month. Also, a strong geostorm will start in mid-September. Therefore, it is important to prepare in time for dangerous dates so that it does not affect health and well-being.

The intensity of magnetic storms is measured internationally using the Kp index. The index value ranges from 0 to 9:

• 0-3 - calm condition;

• 4 - moderate fluctuations;

• 5 and above - start of a magnetic storm or strong storm;
