On Saturday, August 14, a small solar flare erupted on the Sun at about 6 a.m. EDT. Associated with this flare was a coronal mass ejection (CME) that was partially directed towards the Earth. The only impacts expected for a solar radiation storm of this magnitude are minor impacts to high frequency radio communications in the polar regions.
