The Sun emitted a strong solar flare on Nov. 30, 2025, peaking at 9:49 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.9 class: go.nasa.gov/4alXf6P Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel. To see how such sp

🌞 😮 Sun activity for October 30, 2023: AR3474 flaring and a new backside region 👍 Sun activity, while still low😴 , has increased closer to the M flare level. AR3474 developed a small delta region. This is in line with the overall decrease in activity from the region. This region produced all the current flares. 🤔 The region has grown in size along with its increase in magnetic complexity. Region AR3473 has also slightly increased in size and complexity, but not to the level of AR3474. 😎 We
