L’observatoire de dynamique solaire de la NASA a capturé cette image d’une éruption solaire – comme le montre l’éclair brillant au centre de l’image – le 4 mai 2022. L’image montre un sous-ensemble de la lumière ultraviolette extrême qui met en évidence la matière extrêmement chaude des éruptions, et qui est colorée en jaune. Crédit : NASA/SDO
Au cours des dernières 24 heures, le soleil a émis deux éruptions solaires de classe M et une éruption de classe X. Sur l’échelle utilisée pour classer les éruptions solaires, les éruptions de classe X sont les plus intenses, et les éruptions de classe M sont un niveau en dessous. Cela fait suite à plusieurs autres large débordements.
Le Soleil a émis une éruption solaire modérée le 4 mai 2022, avec un pic à 5 heures du matin (ET). ;” data-gt-translate-attributes=”[{” attribute=””>NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. This flare is classified as an M-class flare.
NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash in the lower-left portion of the image – on May 3, 2022. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares, and which is colorized in yellow. Credit: NASA/SDO
The Sun emitted a moderate solar flare on May 3, 2022, peaking at 8:19 p.m. ET. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. This flare is classified as an M-class flare. M-class flares are a class below the most intense flares, the X-class flares.

The Sun emitted a strong solar flare on May 3, 2022, peaking at 9:25 a.m. EDT. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. This flare is classified as an X-class flare. X-class denotes the most intense flares, while the number provides more information about its strength.
Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, and navigation signals. They also pose risks to spacecraft and astronauts. More info on how flares are classified can be found here.
This animation of the Solar Dynamics Observatory shows it above the earth as it faces toward the Sun. SDO is designed to help us understand the Sun’s influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

Please visit NOAA’s Space Weather Prediction Center, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts, to see how such space weather may affect Earth. NASA serves as the nation’s space weather research arm. NASA constantly monitors the Sun and our space environment with a network of spacecraft that investigate everything from the Sun’s activity to the solar atmosphere, as well as the particles and magnetic fields in the space surrounding Earth.
