Over the last 24 hours, the Sun has produced an intense burst of activity, firing at least 18 M-class solar flares along with three powerful X-class flares. The most significant of these was an X8.3 flare, making it the strongest solar eruption recorded so far in 2026. Understanding solar flare intensity Solar flares are sudden releases of energy from the Sun’s surface. X-class flares sit at the top of this scale, and an X8.3 flare ranks among the most extreme events of this kind, according to NASA. Initial evaluations indicate that most of the material from the X8.3 flare is likely to pass by Earth, although a minor impact cannot be ruled out around February 5.
