The Sun is a relatively quiet G-type star (G2V), but the key word is “relatively.” While it avoids the massive storms known to affect so-called flare stars, it occasionally releases both solar flares and coronal mass ejections. On March 20, NASA detected such a flare with an associated CME. The coronal mass ejection will hit Earth on March 23 and may push the northern lights far south, lighting up skies in the northern United States and southern Canada.
