ocr: CME (Coronal Mass Ejection) Coronal mass ejections occur at a rate of a few times a week to several times per day. If a CME erupts on the side of the Sun facing Earth, and if our orbit intersects the path of that cloud, the results can be spectacular and sometimes hazardous. CMES cause disturbances in the magnetosphere, which trigger auroras, make magnetic navigation at high latitudes difficult, and sometimes cause current peaks in high-voltage power lines, resulting in power outages and occasionally in the destruction of power equipment. They can - - also damage or destroy Earth-orbiting sate ...
