First Notable Solar Flare of 2015
Mid-level solar flare on Jan. 12, 2015
NASA

The sun emitted a mid-level solar flare, peaking at 11:24 p.m. EST on Jan. 12, 2015.
NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image 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.
