Photo of the Week -- Two Solar Flares Erupt Within Two Hours

by / June 10, 2014

On June 10, 2014, the sun emitted a significant solar flare that peaked at 4:42 a.m. Pacific Daylight Time on June 10, 2014.

NASA's Solar Dynamics Observatory captured images of that flare, along with the second flare that occurred at 5:55 a.m. PDT, shown below. The SDO even captured the flare in action.

Solar flares release an intense burst of radioactivity into space, but as UPI reported, the waves can't penetrate Earth's atmosphere and harm humans. But they can momentarily disrupt GPS and communication satellites. As the solar physicist Tony Phillips of told the Los Angeles Times, X-rays and UV radiation from the two flares messed with some radio transmissions over Europe.
