Mid-level Solar Flare Erupts from the Sun
The bright light on the left side of the sun shows an M5.2-class solar flare in progress on May 8, 2014.This image, captured by NASA's SDO, shows light with a 131 Angstrom wavelength, which highlights the extremely hot material in a solar flare and is typically colorized in teal.

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.
To see how this event may impact Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, the U.S. government's official source for space weather forecasts, alerts, watches and warnings.
This flare is classified as an M5.2-class flare. M class flares are on the order of a tenth as strong as the most intense flares, the X-class flares.
Updates will be provided as needed.
What is a solar flare and what is M-class?
