Here`s a Coronal Mass Ejection Right Before It Hit Earth
(World News Science)

By Miles Hatfield NASA`s Goddard Space Flight Center On Aug. 20, 2018, a Coronal Mass Ejection - an explosion of hot, electrically charged plasma erupting from the Sun - made its way towards Earth. By Aug. 26 it had hit - and aurora were visible as far south as Montana and Wisconsin in the United States. NOAA`s DSCOVR satellite (short for Deep Space Climate Observatory) watched it all go down. DSCOVR`s measurements track magnetic field strength and direction - two aspects of a CME that determine how much it will affect Earth. These data, and the unique view of a CME that they provide, are why DSCOVR is such a useful tool for NASA`s space weather forecasters, detecting CMEs between 15 minutes...
