Start of the May 2024 Solar Storms, the most powerful set of Geomagnetic storms since the 2003 Halloween solar storms.

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 to 13 May 2024 during solar cycle 25. They are also known as the 2024 Mother's Day solar storm or the Gannon storm. The geomagnetic storm was the most powerful to affect Earth since March 1989, and produced aurorae at far more equatorial latitudes than usual in both the Northern and Southern Hemispheres.

The Halloween solar storms were a series of solar storms involving solar flares and coronal mass ejections that occurred from mid-October to early November 2003, peaking around October 28–29. This series of storms generated the largest solar flare ever recorded by the GOES system, modeled as strong as X45.

May 10 is the 130th day of the year in the Gregorian calendar; 235 days remain until the end of the year.
