Summary
| Description | On April 2, 2014, the sun emitted a mid-level solar flare, peaking at 10:05 a.m. EDT, and NASA's Solar Dynamics Observatory captured imagery of the event. 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 video from NASA's Solar Dynamics Observatory shows the flare in a blend of two wavelengths of extreme ultraviolet light: 304 angstroms and 171 angstroms, colorized in red and yellow, respectively. |
