Track recent solar flare events detected by NASA. Solar flares are sudden eruptions of electromagnetic radiation from the Sun, classified by their X-ray brightness.
Solar flares are sudden, intense bursts of electromagnetic radiation originating from the Sun's surface near sunspot groups. They occur when built-up magnetic energy in the solar atmosphere is suddenly released through a process called magnetic reconnection. Flares are classified by their peak X-ray flux: B-class (the weakest), C-class (moderate, rarely noticed on Earth), M-class (medium-sized, can cause brief radio blackouts at the poles), and X-class (the most powerful, capable of causing planet-wide radio blackouts and long-lasting radiation storms). The classification uses a logarithmic scale — an M-class flare is 10 times stronger than a C-class. Each class is further divided into a linear scale from 1 to 9 (except X-class, which has no upper limit). The strongest flare ever recorded was an X28+ event on November 4, 2003, during the "Halloween Solar Storms."
