   Explanation: This almost [5]otherworldly display of northern lights was
   captured in clear skies during the early hours of March 31 from 44
   degrees north latitude, planet Earth. In a five second exposure the
   scene looks north from Martinique Beach Provincial Park in Nova Scotia,
   Canada. Stars of the W-shaped constellation Cassiopeia shine well above
   the horizon, [6]through the red tint of the higher altitude auroral
   glow. Auroral activity was anticipated by skywatchers alerted to the
   possibility of [7]stormy space weather by [8]Sun-staring spacecraft.
   The predicted geomagnetic storm was sparked as a coronal mass ejection,
   launched from [9]prolific solar active [10]region 2975, impacted our
   [11]fair planet's magnetosphere.
