The solar storms of May 2024 were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25. The geomagnetic storm was the most powerful to affect Earth since March 1989,[a] and produced aurorae at far more equatorial latitudes than usual in both the Northern and Southern Hemispheres.[1][2]
