[Regnum] The strongest magnetic storm in the last three months has begun on Earth at the moment. This was reported on Monday, September 15, by the press service of the Solar Astronomy Laboratory of the Space Research Institute (IKI) of the Russian Academy of Sciences.

"A strong magnetic storm, close to G3, is being observed on Earth. The event is being recorded against the background of a noticeable increase in the speed of the solar wind as a result of the planet entering the zone of a large coronal hole, the boundary of which the Earth crossed yesterday around midnight," the laboratory's website says.

According to scientists, the magnetic storm was predicted several days ago, but its strength turned out to be much higher than expected. The last time such a disturbance of the Earth's magnetosphere was observed was in early June, that is, more than three months ago.

The IKI RAS laboratory clarified that the geomagnetic situation will continue to deteriorate over the next 4–6 days and its full normalization is expected no earlier than September 18–19.

At the same time, scientists added that the local current surge could end within 6-9 hours.

On September 12, scientists warned that a six-day magnetic storm was expected on Earth, which was caused by a coronal hole on the Sun. According to the IKI RAS laboratory, a large coronal hole appeared on the star, creating a wide flow of fast solar wind, the full impact of which on Earth could take up to six days.
