The winner of the solar Olympics 🏅 In this video, you're seeing sped-up footage of the most productive region on the Sun this year so far, active region AR4366. The loops of hot plasma shown here reach temperatures of around 600,000 Kelvin, or a scorching 1 million degrees Fahrenheit. This imagery was captured by our Solar Dynamics Observatory (SDO) between Feb. 1 and Feb. 9 in 2026. During this window, AR4366 produced 75 M-class and six X-class flares, the two largest classes of solar flares.
