Scientists have reported a sudden magnetic storm on Earth.

The geomagnetic disturbances provoked by the coronal hole in the Sun have reached the level of a magnetic storm, which came as a surprise to scientists. This was announced on October 31 at the Laboratory of Solar Astronomy at the Institute of Space Research (IKI) of the Russian Academy of Sciences.

"Unexpected, to put it mildly. <...> A G2—level planetary magnetic storm began less than an hour ago," the Telegram channel says.

Experts also noted that due to geomagnetic disturbances, maximum-level auroras are observed over Russia.

On October 31, the laboratory explained that the Earth was trapped in a stream of plasma emanating from a coronal hole in the Sun. According to observations, the plasma temperature in the vicinity of the Earth has increased dramatically — from about 30 to 200 thousand degrees. The coronal hole itself is large. Scientists believe that it will remain a factor influencing space weather over the next two to three days.
