Overview

  • An X2.7-class solar flare erupted on May 14, 2025, marking the most powerful solar event of the year so far.
  • The flare caused R3-level radio blackouts across Europe, Asia, and the Middle East, along with minor power degradation in the eastern U.S.
  • NASA and NOAA warn of potential ongoing impacts to communications, power grids, navigation systems, and risks to astronauts and satellites as solar activity remains elevated.
  • Sunspot AR4087, the source of the flare, is rotating into a more Earth-facing position, increasing the likelihood of further disruptive flares.
  • Enhanced auroras are forecast across northern U.S. states, with solar maximum conditions expected to drive heightened activity into 2026.
