Increase in Solar Activity: Scientists Issue Warning

On August 29, 2025, a powerful solar flare of class M1.1 was recorded. This was reported to TASS by the Federal State Budgetary Institution "Institute of Applied Geophysics" (FGBU "IAG"), which specializes in solar-terrestrial relations.

According to the institute:
"At 07:16 Moscow time, an M1.1-class flare with a duration of 9 minutes was registered," the agency said.

The Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences (IKI RAS) and the Institute of Solar-Terrestrial Physics of the Siberian Branch of RAS (ISTP SB RAS) also noted that on August 29 there is a high likelihood of strong solar flares that could affect Earth. 

Classification of Solar Flares

Solar flares are classified into five categories based on X-ray radiation intensity: A, B, C, M, and X.

  • Class A is the weakest, where A0.0 equals 10 nanowatts per square meter of radiation at Earth’s orbit.

  • Each next class increases in intensity tenfold.

Although M-class flares are considered medium strength, they may also involve significant ejections of solar plasma. If these clouds reach Earth's atmosphere, they can trigger geomagnetic storms

Atmospheric and Geomagnetic Interactions

In August, American scientists announced that the increase in carbon dioxide (CO₂) in the upper layers of the atmosphere may alter the way geomagnetic storms affect Earth. This could influence the operation of thousands of satellites in orbit.

Scientists have previously warned that the impact of magnetic storms on Earth is intensifying.
