Sun Releases 2 Strong Solar Flares

The Sun emitted two strong solar flares, peaking at 5:40 p.m. ET on May 8, 2024, and 5:13 a.m. ET on May 9, 2024. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured images of the events.

On the left, a teal Sun against a black background. The Sun has bright spots, especially on the far left and far right, but the brightest spot is slight to the right of center. There there is a bright flash — the flare. On the right, the same Sun, shown in red. The bright flash of the second flare is in the same spot as the first. — NASA’s Solar Dynamics Observatory captured these images of the solar flares – as seen in the bright flash in the lower right – on May 8, 2024 (left) and May 9, 2024 (right). The images show a subset of extreme ultraviolet light that highlights the extremely hot material in flares. The left image is colorized in teal and the right image is colorized in red.

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 X1.0 flare and the second flare is classified as an X2.2 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.
