The Sun emitted a strong solar flare on October 7, 2024, peaking at 3:13 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X2.1. 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.
