Planetary-scale magnetic storms have been recorded on Earth. Around midnight Moscow time, the geomagnetic index Kp reached values from G2 to G3, which corresponds to medium and strong disturbances of the magnetic field, according to the Solar Astronomy Laboratory of the Russian Academy of Sciences.
The cause of the storms was plasma ejections from the Sun, which occurred 2–3 days ago in active areas located on the edge of the solar disk. Despite the remote location, plasma clouds are moving towards Earth at greater angles and speed than expected, which complicates the forecast and increases the risk of increased geomagnetic activity.
According to researchers, the current disturbances will last about a day and will likely move into a more powerful phase tomorrow, when the main mass of solar plasma reaches Earth. This will lead to increased magnetic storms and possible consequences for electronics, communications and navigation systems.
The event is important for a wide audience, as strong magnetic storms can affect the operation of satellites, radio communications, power grids, and even the well-being of people, especially those who are weather-sensitive.
