Sun Releases Three Strong Flares

The Sun emitted three strong solar flares. The first flare peaked at 2:01 A.M. ET on May 5, 2024, and the second peaked at 7:54 A.M. ET on May 5, 2024. The third peaked at 2:35 A.M. ET on May 6, 2024. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

The first flare is classified as an X1.3 flare. The second flare is classified as an X1.2 flare. The third flare is classified as an X4.5 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

NASA works as a research arm of the nation’s space weather effort. NASA observes the Sun and our space environment constantly with a fleet of spacecraft that study everything from the Sun’s activity to the solar atmosphere, and to the particles and magnetic fields in the space surrounding Earth.
