The Solar Astronomy Laboratory of the Russian Academy of Sciences announced that a large cloud of solar plasma is approaching Earth and may trigger geomagnetic storms affecting our planet, according to Russia Today.

Scientists noted that a strong solar flare on October 3 caused the Sun to eject a plasma cloud. The cloud has been moving relatively slowly and has not yet significantly impacted Earth’s magnetic field, but its effects on the planet’s atmosphere may become noticeable by Wednesday.

A statement from the laboratory said: “The plasma cloud is expected to begin affecting Earth’s magnetic field on Wednesday, potentially causing disturbances that could last a day or more. There is still a high likelihood of minor geomagnetic storms occurring soon”.

On the morning of October 3, the Solar Astronomy Laboratory reported observing a strong M1.5-class solar flare that ejected a large plasma cloud from the Sun. On October 7, astronomers observed the first signs of the cloud approaching Earth’s magnetic field.

Geomagnetic storms on Earth occur due to increased solar activity. They can disrupt power systems, affect the migration paths of birds and animals, and, in the case of strong storms, interfere with communication and navigation systems. The intensity of geomagnetic storms is classified into five levels based on disturbances in Earth’s magnetic field, ranging from G1 (weak) to G5 (extremely strong).
