 Double Rainbow over Freital, Germany

   November 04, 2021

   Summary Author:  Heiko Ulbricht;  Cadan Cummings

   Weather around the town of  Freital in eastern Germany this past May
   felt like a continuation of the typical April spring weather- rain,
   sun, and brief thunderstorms. However, on the evening of May 16, 2021,
   a beautiful sight could be seen on the horizon after a rather large
    weather cell passed over from  Freiburg, Germany. The weather
   radar showed a large cloud-free zone behind the storm with the ideal
   conditions for a rainbow. Preparing the camera in peace and quiet, one
   could take their time positioning and waiting for an almost certain
   rainbow to appear overhead. Luckily, the weather radar and predictions
   were correct and the region was treated to a beautiful  primary and
   secondary rainbow.

   In order for a double rainbow to be visible, specific atmospheric
   conditions must be present. Primarily, larger water droplets must be
   suspended in the air in order for a double reflection to occur.
   Additionally, the rainbow must be exactly opposite in the sky to the
   solar disk from the viewer’s perspective, also called the  antisolar
   point. Adding to the spectacle of a double rainbow is a region of
    Alexander’s Dark Band between the primary and secondary rainbows.
   This comparably darker area is caused by the water droplets between the
   two rainbows  scattering light away from your eyes.
