Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X2.2 flare. X-class denotes the most intense flares, while the number provides more information about its strength.
