X-class solar flare observed on 18 January 2026 Composite view of the solar flare and its associated Coronal Mass Ejection erupting on 18 January 2026. This GIF combines observations of the Sun across three different wavelengths (121 Å, 193 Å, 204 Å). The images were obtained by the AIA instrument onboard NASA's Solar Dynamics Observatory and combined using ESA's JHelioViewer. | ESA - European Space Agency

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
