The sun emitted a mid-level solar flare, peaking at 6:07 a.m. EDT on May 8, 2014, and NASA’s Solar Dynamics Observatory, or SDO, captured images of it. 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.

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.
