   During the afternoon of February 15, 2022, I was lucky enough to see a
    supernumerary rainbow in the sky over  Modica, Sicily, Italy.
   These unique rainbow arcs are visible below the  primary rainbow and
   are produced when incoming sunlight is  diffracted through very
   small raindrops. Resulting from the diffraction process are regions of
    light wave interference where the colorful band are from
   constructive interference and the colorless gaps are from destructive
   interference.

   Supernumerary rainbows can be identified by several colored fringes-
   ranging from indigo to green- visible below the rainbow that also
   appear like the rainbow is repeating itself. To show the optical
   phenomenon in greater detail, I enlarged the part that had the
   supernumerary arcs and  saturated it a little to highlight the
   features and colors. This specific composite image is a panorama
   composed of eight vertical shots taken using a Nikon DSLR camera with a
   35mm lens.
