The Sun emitted a strong solar flare on April 30, 2022, peaking at 9:47 a.m. EDT. 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, and navigation signals. They also 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. More info on how flares are classified can be found here.
