Earth is experiencing the strongest magnetic storm in the last three months. The Solar Astronomy Laboratory reported this on September 15.
The event is related to the planet's entry through the zone of a large coronal hole that crossed the border on the night of September 15.
According to experts, such an increase in geomagnetic activity was unexpected. Weak impairments not exceeding the G1 level were previously predicted, but the latter event turned out to be much higher. A similar storm was observed on June 1-2 of this year, that is, more than three months ago.
The general deterioration of the geomagnetic situation is expected to last approximately 4-6 days, and the situation in near-Earth space may fully normalize by the end of this week.
Experts note that the impact of coronal holes is not entirely stable: the storm usually develops in the form of separate explosions lasting several hours, among which a temporary weakening of activity is also observed. According to preliminary estimates, the current local activity is likely to decrease within the next 6-9 hours. However, experts note that it is difficult to accurately predict the development of events and there may be deviations from forecasts.
As a reminder, it was previously reported that starting from the end of last week, Earth would enter the solar wind flow emerging from a large coronal hole in the Sun. Based on this, it was predicted that geomagnetic disturbances could last up to six days, with their peak occurring on September 14-16.
