 Inferior Mirage of Amerigo Vespucci

   October 21, 2022

    Miraggio Inferiore amerigo L

   Photographer:  Marcella Giulia Pace

   Summary Author:  Marcella Giulia Pace

   Shown above is a sailing ship, the  Amerigo Vespucci, that was
   miraged on the horizon of the Ragusa Coast of Sicily, Italy.  This
   photo was taken from the seafront of  Marina di Ragusa (Sicily) at a
   height of about 9 m, and therefore the visible horizon was about 10 km
   distant. Thus, the Earth's curvature actually conceals most of the
   ship. Layers of warm air, beneath layers of cooler air generated this
    inferior mirage, in which the visible parts of the ship are flipped
   downward. This “overturning” made the ship's bowsprit appear like a
   great, open mouth advancing towards the sea.

   Note that the  "Amerigo Vespucci", an Italian military school ship,
   dates from 1931.  Click here to see a video of this mirage. Photo
   taken on August 28, 2022.

   Photo details: Nikon D750 camera; sigma 150-600mm lens; 1200 focal);
   1/640 second exposure; f13; ISO 100.
