Another strong geomagnetic storm has begun on Earth. Following a solar flare this morning, geomagnetic fluctuations sharply intensified, reaching a level of 7.33, which corresponds to a strong G3-class storm. The last time similar fluctuations occurred was on June 1, according to data from the Solar Astronomy Laboratory of IKI RAS and the Institute of Solar-Terrestrial Physics SB RAS.
Scientists remind that strong G3-class geomagnetic storms can affect power systems, including triggering false protection responses, as well as impact spacecraft, causing increased orbital decay. Interruptions in satellite navigation, problems with low-frequency radionavigation, and disruptions of HF radio communication are also possible.
