UNEXPECTED Strong geomagnetic storm hits Earth »

The storm was being called ‘unexpected’ .. This is how SPACE WEATHER documented today’s event:

UNEXPECTED GEOMAGNETIC STORM: A strong G3-class geomagnetic storm erupted during the early hours of Jan. 7th, sparking bright auroras around Earth’s poles. What happened? The interplanetary magnetic field (IMF) near our planet tipped south, opening a crack in Earth’s magnetosphere. Solar wind poured in to fuel the strongest magnetic storm since Sept. 2014. NOAA analysts believe the fluctuation in IMF is related to the arrival of a CME originally expected to miss Earth. Browse the aurora gallery for pictures of the event. 

The geomagnetic storm is the strongest to hit Earth since September..
