The Sun emitted a strong solar flare that peaked at 11:19 p.m. EDT on March 29, as captured by NASA’s Solar Dynamics Observatory. Solar flares are powerful bursts of energy that can impact various systems on Earth, such as radio communications, electric power grids, navigation signals, and even spacecraft and astronauts.
The recent flaring activity is not expected to affect the Artemis II mission at this time, but NASA continues to monitor space weather activity as they prepare for the launch. This particular flare has been classified as an X1.4 flare, with X-class denoting the most intense flares and the number providing information about its strength.
For more information on how space weather may affect Earth, you can visit NOAA’s Space Weather Prediction Center, which is the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts. NASA plays a crucial role in researching space weather and constantly observes the Sun and our space environment with a fleet of spacecraft.
