Sun unleashes back-to-back X-class flares in 7 hours, radio outages hit Earth

NASA reported two back-to-back X-class solar flares from sunspot AR4419 within seven hours.

The X2.4 and X2.5 eruptions disturbed the ionosphere and caused shortwave radio outages across parts of the Pacific, Australia, and East Asia.

The brief blackouts underscore how strong space weather can disrupt communications, navigation, power systems, and satellites during Solar Cycle 25.
