Surprise Geomagnetic Storm

Space Weather News for March 19, 2018 http://spaceweather.com https://www.facebook.com/spaceweatherdotcom SURPRISE GEOMAGNETIC STORM: On March 18th, an unexpected crack opened in Earth's magnetic field, sparking a brief but potent G2-class geomagnetic storm. Bright auroras ringed the Arctic Circle while, in Europe, the light show descended as far south as Germany. With the northern vernal equinox less than a day away, this is the time of year when such cracks tend to form. Today's edition of Spaceweather.com explains the phenomenon of springtime magnetic cracks and how you can monitor them online. Remember, SpaceWeather.com is on Facebook!
