Sun unleashes 2 colossal X-class solar flares, knocking out radio signals across the Americas and Pacific

Two panel image showing the location of the two X-class solar flares from Nov. 4 2025.

The sun has fired off not one but two colossal X-class solar flares in less than 12 hours, causing radio blackouts across the sunlit portion of Earth at the time of eruption and marking a dramatic uptick in solar activity.

Each of the X-flares was accompanied by a coronal mass ejection. (Image credit: NOAA SWPC / LASCO)
