Brief By Space.com / 11:20 AM on 17 Aug 2026

A coronal mass ejection triggered by a solar eruption on August 14 is expected to reach Earth on August 17, potentially producing a G1-class geomagnetic storm. The minor storm could generate auroras at high latitudes and temporarily affect satellites, radio communications and navigation systems. However, no significant impact on the public is expected, while experts monitor conditions around the world.
