NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash in the upper left portion of the image– on April 16, 2022. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares, and which is colorized in SDO channel color AIA 304.

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 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.
