There Is A Green Flash At Sunset!!
       
      
      Sue's Green Flash
    
      Sue taught me about the "Green Flash"... and it DOES EXIST... we have seen it many times! 
      
      Explanation: Many think it is just a myth. Others think it is true but its cause is not known. Adventurers pride themselves on having seen it. It's a
      green flash
      from the
      Sun
      .
      
       The truth is the
      green flash
      does exist and its cause is well understood. Just as the setting
      Sun
      disappears completely from view, a last glimmer appears startlingly
      green
      . The effect is typically visible only from locations with a low, distant horizon, and lasts just a few seconds. 
      
      A
      green flash
      is also visible for a rising
      Sun
      , but takes better timing to spot. A dramatic green flash was caught in the above photograph in 1992 from
      Finland
      . The
      Sun
      itself does not turn partly green, the effect is caused by layers of the
      Earth's atmosphere
      acting like a
      prism
      .
