Une puissante éruption solaire de classe X jaillit du Soleil – Captée par l’observatoire de la dynamique solaire de la NASA

Eruption solaire SDO le 30 avril 2022

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 avril 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 rouge. Crédit : NASA

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. More info on how flares are classified can be found here.

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.
