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

  • On May 14, 2025, sunspot region AR 4087 emitted the strongest solar flare of the year, an X2.7-class event causing radio blackouts globally.
  • This flare occurred during the solar maximum phase, when the Sun regularly produces powerful flares and heightened magnetic activity involving AR 4087.
  • The solar flare reached its peak at 08:25 UTC from the Sun’s eastern edge, releasing a strong burst of X-rays and ultraviolet light that ionized Earth’s upper atmosphere and caused disruptions to radio communications.
  • NOAA designated the flare as an R3-level event, reporting that those relying on high-frequency radio communications experienced temporary outages across parts of the sunlit regions spanning the Eastern Hemisphere.
  • While no major geomagnetic storms are expected, AR 4087’s continued activity could cause further space weather effects as it rotates toward Earth next week.
