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 on 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.
