Specialists from the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences and the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences are warning of geomagnetic disturbances that could affect Earth over the next three days—from Friday to Sunday. The probability of these events is estimated at 90%.

According to scientists, the Earth's magnetosphere is expected to transition from a calm state to a disturbed one on April 10. This will be caused by the influence of a coronal hole on the Sun. On the night from Friday to Saturday, the storm may intensify due to a weak coronal mass ejection approaching the planet.

A moderate G2 storm with a Kp index of 5 is expected on April 11. Magnetic storms are also predicted on April 17, 29, and 30, and magnetospheric disturbances are predicted on April 11, 16, from April 18 to 21, as well as on April 25 and May 1.

Magnetic storms are strong fluctuations in the Earth's magnetic field caused by solar activity. During peak periods, minor disruptions to power systems, interference with radio communications and satellite navigation, and the appearance of auroras at high latitudes are possible.

Experts remind us that long-term forecasts are subject to change—the most accurate data can be obtained no more than three days before an event, as solar activity can be unpredictable.

Up-to-date information on the state of the geomagnetic field is published on the website of the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences.
