L’observatoire de dynamique solaire de la NASA a capturé cette image d’une éruption solaire – comme le montre l’éclair brillant vers le milieu du Soleil – le mardi 10 mai 2022. L’image montre un sous-ensemble de lumière ultraviolette extrême qui met en évidence la matière extrêmement chaude des éruptions et qui est colorée en sarcelle. Crédit : NASA/SDO
Le Soleil a émis une forte éruption solaire de classe X le mardi 10 mai 2022, avec un pic à 9 h 55 HAE. ;” data-gt-translate-attributes=”[{” attribute=””>NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.
Activity on the sun has picked up dramatically in recent days, with many strong and moderate solar flares erupting.
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.

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.
