L’observatoire de dynamique solaire de la NASA a capturé cette image d’une éruption solaire – comme le montre l’éclair brillant dans la partie supérieure droite de l’image – le 30 mars 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 (AIA 171). Crédit : NASA
Le Soleil a émis une éruption solaire importante le 30 mars 2022, avec un pic à 13 h 35 HNE. ;” data-gt-translate-attributes=”[{” attribute=””>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.
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. An X2 is twice as intense as an X1, an X3 is three times as intense, etc. More info on how flares are classified can be found here.
To see how such space weather may affect Earth, please visit NOAA’s Space Weather Prediction Center, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts. 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.
