 Twinned Rainbow

   December 13, 2022

   Summary Author:  Facundo Jauri

   The rainbow panorama above, composed of 4 photos, was captured over
   Quilmes, Buenos Aires. It was taken looking east at 17:29 (local time)
   on September 22, 2022. Notice how this bow appears to split along the
   highest portion of the arch, creating a different rainbow but with the
   same color pattern as the  primary rainbow, unlike a normal double
   rainbow where the  secondary outer bow has a reverse color pattern
   than the primary bow. This is known as a  twinned rainbow. It's not
   known for certain just how these bows form, but  model simulations
   suggest that rain showers having slightly different shaped and sized
   raindrops (spherical and oblate, for instance) could explain their
   formation.

   Photo details: Canon 6D camera; Canon lens 50 mm; f/8; 1/4000 exposure;
   ISO 800; stitched and processed in Photoshop.
