The Sun emitted two strong solar flares, the first peaking at 9:07pm ET on April 23 and the second peaking at 4:13am ET on April 24. NASA’s Solar Dynamics Observatory captured images of the events, which were classified as X2.4 and X2.5:

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.
