This month, the main source of magnetic storms has been coronal holes on the Sun. The exception was the most powerful storm, which lasted from January 19 to 21. It was caused by the impact of a plasma cloud ejected as a result of an X1.9 class solar flare that occurred on January 18.
With the beginning of February, there has been a temporary decrease in geomagnetic activity: only one magnetic storm was recorded in the first week of the month. Despite this, a recent powerful surge in solar activity, one of the most significant in the 21st century, had almost no impact on Earth, although it was accompanied by several major flares.
The reasons for this situation remain unclear, but forecasts suggest that the situation may change soon, as new coronal holes are approaching Earth.
