The sun has recently emitted several strong solar flares, prompting experts to watch for northern lights and potential satellite disruptions.

On Sunday and Monday, NASA recorded four X-class flares—the most intense type—with one reaching X8.1, the strongest in several years.

These flares can briefly disrupt high-frequency communications on the sunlit side of Earth and may precede Coronal Mass Ejections (CMEs).

When interacting with Earth’s atmosphere, solar flares can produce auroras, though visibility depends on CME orientation, arrival, and local weather, ABC News has reported.

NOAA expects heightened solar activity from sunspots to continue through 2026, sustaining a higher frequency of northern lights displays.
