On the scale where G5 indicates "extremely strong" and G1 indicates "weak," a G3 level suggests possible disruptions in energy systems. This may lead to false alarms in safety mechanisms and overheating of oil transformers. Issues with satellite navigation and high-frequency radio communication are also expected. In some regions, polar auroras may be visible.
Experts from the Solar Astronomy Laboratory of the Institute of Space Research of the Russian Academy of Sciences explained that the cause of this phenomenon was plasma ejections that reached Earth.
According to experts, the storm and related disturbances may last for about a day and are unlikely to cease, as a significant influx of plasma is expected soon, which will lead to new geomagnetic processes.
