Solar Dynamics Observatory Captures Images of a Late
Summer Flare
On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16
a.m. EDT. NASA's Solar Dynamics Observatory captured images of the flare, which
erupted on the left side of the sun. Solar flares are powerful bursts of
radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere
to physically affect humans on the ground, however -- when intense enough --
they can disturb the atmosphere in the layer where GPS and communications
signals travel. This flare is classified as an M5 flare. M-class flares are ten
times less powerful than the most intense flares, called X-class flares.
