Washington: The sun emitted a mid-level solar flare late Monday night, peaking at midnight.
This image, captured by NASA`s Solar Dynamics Observatory, shows the bright flare near the center of the sun.
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.
