Veteran's Day Solar Flare

NASA's Solar Dynamics Observatory captured this image of 
an X1.1 class flare in the early hours of Nov. 10, 2013. 
The image represents light with a wavelength of 131 
Angstroms, which is typically colorized in teal.

The sun emitted a significant solar flare that peaked at 1:14 a.m. EST on Nov. 10, 2013. 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.
