Earth-directed Coronal Mass Ejection from Sun | NASA’s SDO

The Sun emitted an Earth-directed coronal mass ejection (CME) on July 21, 2024. NASA’s Solar Dynamics Observatory (SDO), watching the Sun constantly in extreme ultraviolet light, captured images of the event (see brief, bright flash at upper left). 

A CME is an eruption of solar material. When they arrive at Earth, a geomagnetic storm can result. A G2 geomagnetic storm watch has been issued. Watches of this level are uncommon. The effects of the CME are expected on July 24. 

To see how such space weather may affect Earth, please visit the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center: https://spaceweather.gov

NOAA is 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.
