Sun Launches Its Strongest Solar Flare of the Year So Far, Causing Radio Blackouts Around the World

  • On May 14, 2025, sunspot region AR4087 unleashed a powerful X2.7 solar flare that led to severe radio signal disruptions throughout much of Europe, Asia, and especially the Middle East.
  • This event occurred during the solar maximum phase of the Sun's 11-year cycle, when heightened magnetic activity triggers frequent flares and sunspot eruptions.
  • The flare reached its maximum intensity at 08:25 UTC, emitting strong X-ray and ultraviolet energy that affected Earth's upper atmosphere, causing disturbances to high-frequency radio communications on the daylight side of the planet.
  • NOAA classified the event as an R3-level radio blackout and noted the highest blackout concentration occurred in the Middle East, with users experiencing signal degradation or loss.
  • While the flare is the strongest so far this year, further eruptions from AR4087 as it rotates toward Earth may impact geomagnetic activity and auroral displays next week.
