The Sun emitted two solar flares on April 19, 2022. One was moderate (M-Class) peaking at 9:35 p.m. EST and one was strong (X-Class) peaking at 11:57 p.m. EST. NASA’s Solar Dynamics Observatory (SDO), which watches the Sun constantly, captured images of both events.
Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, and navigation signals, and pose risks to spacecraft and astronauts.
The flare pictured above is classified as an M-Class flare. M-class flares are a class below the most intense flares, the X-class flares. The number provides more information about its strength. More info on how flares are classified can be found here.
The flare pictured above is classified as an X-Class flare. X-class denotes the most intense flares.

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.
