From October 7 to October 9, increased solar activity is expected, which is marked by K-Index at 4.7 in the first two days and 3 in the third. Magnetic storms can significantly affect atmospheric pressure and cause headache, fatigue and stress.
This is evidenced by the data of the space forecasting center (SWPC) NOAA.
Geomagnetic activity is measured on a scale from 0 to 9, Alya designation is used planetary K-index. What is 5 and above – it is a strong magnetic storm.
On Tuesday, October 7, solar activity with K-index is expected 4.7 (yellow level), which corresponds to the average magnetic storm.
On Wednesday, October 8, solar activity with K-index 4.7 (yellow level) is expected, which corresponds to the average magnetic storm.
On Thursday, October 9, solar activity with K-index 3 (green level) is expected, which corresponds to weak magnetic storms.
It is important to note that magnetic storms forecasts can change as solar activity researchers update their data every three hours.
