    Multicolored Aurora Over Finland

      The photo above features a beautiful  aurora display that occurred   
      over Finland on February 11, 2022. This aurora event occurred due to   
      energetic particles emitted from a  coronal mass ejection on   
       February 6^th interacting with the Earth’s  magnetosphere.   
      Although our planet’s magnetic field protects us from the  solar   
      wind, the energetic particles from  geomagnetic storms are steered   
      towards the  north and south magnetic poles where they interact with   
      oxygen molecules in the  upper atmosphere to create a spectacular   
      green and red display.   
      
      To get a clear view of the event, I packed my gear and cycled a few   
      kilometers to a swamp area located in middle of a forest. After around   
      one hour of waiting, I saw something I had never seen before. Half of   
      the sky began to be covered in faint  red auroras. I knew something   
      huge was about to happen and remarkably the sky came raining down with   
      vibrant auroras. At around midnight the auroras had escaped to the   
      south horizon, giving people in south- and mid-Finland an impressive   
      display as well.
