WASHINGTON: The sun fired off a midlevel solar flare early this morning (Aug. 24) while a NASA satellite watched.
The space agency’s Solar Dynamics Observatory (SDO) captured an image of the flare, which erupted at 3:33 a.m. EDT (0733 GMT) this morning from an Earth-facing sunspot known as Active Region 2403.
Space-weather researchers classify strong flares into three categories — C, M or X. X flares are 10 times more powerful than M flares, which in turn are 10 times more intense than C eruptions. This morning’s outburst registered as an M5.6, NASA scientists said. (An M5 flare is five times more powerful than an M1.
