Auroras often occur when a CME hits Earth
    Often called the northern or southern lights, these often colorful and flashing light displays in the night sky are mostly seen at high latitudes near the poles.  They are caused by the impact of fast moving electrons from outer space (our magnetosphere) on the Earth's upper atmosphere.
