A solar flare of the highest classification has been recorded. Should we expect geomagnetic storms?
An X-ray flare occurred on the northwestern edge of the Sun.
Satellites, orbital observatories, and other devices monitoring the Sun from space recorded a flare classified as the highest possible category, X. Scientists assessed its level at X2.
The flare, which took place at the end of February 23, 2025, does not pose significant risks. It erupted on the northwestern edge of the solar disk but on its far side. Experts from the American space agency (NASA) and the National Oceanic and Atmospheric Administration (NOAA) assure that if a coronal mass ejection occurs from that region, it will not reach Earth. Therefore, no geomagnetic storm is expected. However, disruptions in radio communications may occur due to the impact of extreme ultraviolet radiation.
The flare on February 23 was of the highest possible class.
The Institute of Solar-Terrestrial Physics of the Russian Academy of Sciences and the Institute of Space Research also provide a calm forecast.
Scientists also remind us that not long ago, the Sun was much more active: in May of last year, it emitted a flare at the level of X8.7. A coronal mass ejection hit Earth and triggered a geomagnetic storm of the highest – fifth – level. In September 2017, the Sun flared for over a week with bursts reaching X9.3. Humanity was gripped by fear. The geomagnetic storms generated by these flares caused voltage spikes and failures in electrical grids. Some citizens experienced blown fuses, while those sensitive to weather changes suffered from headaches, rapid heart rates, and elevated blood pressure. But overall, as they say, it turned out fine. And now – it has passed without incident.
