Russian scientists from the Laboratory of Solar Astronomy at the Space Research Institute and the Institute of Solar-Terrestrial Physics (Siberian Branch of the Russian Academy of Sciences, RAS) have issued a warning about a rapid increase in the Sun`s flare activity.
According to the RAS, since the middle of July 11, a significant increase in the number and area of active regions on the Sun has been observed. This growth includes areas on the far side of the Sun, not visible from Earth but currently monitored by the European Solar Orbiter spacecraft. Scientists noted, “In other words, the growth in activity is global in nature.”
The report added that in less than two days from that point, the Sun experienced 17 flares. This indicates a threefold amplification of activity compared to the average levels for July. Scientists currently state that this does not pose a direct threat to Earth or its inhabitants.
Earlier, in late June, a powerful solar flare was recorded, which was the third strongest in 2025. However, the energetic charged particles capable of affecting spacecraft did not reach Earth on that occasion.
