The geomagnetic situation on Earth will significantly worsen on June 12 and 13 – the planet is expected to experience weak G1-level magnetic storms. The cause will be two solar factors simultaneously: a stream of particles from a large coronal hole and a cloud of plasma ejected after a powerful solar flare recorded on June 11.
According to solar activity specialists, the first half of the month was relatively calm, but the current surge in activity could drastically change the situation. The main peak of disturbances is expected on June 13, when the impact of high-speed solar wind will be compounded by the arrival of a coronal mass ejection.
Under such conditions, Earth's magnetic field reacts with increased instability. Although a G1 level is considered weak, such events can affect satellite systems, radio communications, and navigation, as well as cause short-term fluctuations in power grids at high latitudes.
Solar flares are classified by X-ray radiation power and are divided into classes from A to X, where each subsequent class is approximately ten times stronger than the previous one. The most powerful flares are often accompanied by plasma ejections, which, upon reaching Earth, cause geomagnetic storms.
