NASA : The Sun Produced a Flurry of Flares This Week (August 2014)

Images from NASA's Solar Dynamic Observatory (SDO) show it was a busy week on the surface of the sun. It began began with an explosive mid-level flare that erupted last Sunday (August 24). The sun continued to unleash over half a dozen more flares within the next two days. The SDO captured images of the flares, which erupted from a sunspot is known as AR2151. 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.
