The Sun emitted a strong solar flare, peaking at 4:25 p.m. EDT (1:25 p.m. PDT) on October 2, 2022. NASA’s Solar Dynamics Observatory, which constantly watches the Sun, captured an image of the event (see above).
Solar flares are powerful bursts of energy from the Sun. Flares and solar eruptions can pose risks to spacecraft and astronauts. They can also affect things on Earth including radio communications, navigation signals, and electric power grids.
This flare is classified as an X1 flare. X-class denotes the most intense flares, while the number provides more information about its strength. More information on how flares are classified can be found here.
