 Double Cloud Shadow off the Coast of Croatia

   December 06, 2022

   Photographer:  Maja Kraljik
   Summary Author:  Maja Kraljik;  Jim Foster
   As I photographed a  cumulus congestus cloud over the northwestern
   Adriatic Sea, off the coast of Croatia, I noticed that it was backlit
   by the near mid-day Sun. As this cloud grew and developed, an
   eye-catching double  shadow began to appear immediately above it.
   Projected shadows may be observed when the cloud’s shadow is cast upon
   a thin layer of  dust,  haze or other  aerosols. In this case
   the source of dust was likely the Sahara Desert. Such shadows are
   typically seen when  looking within about 10 degrees of the solar
   disk. Note also the  crepuscular rays -- above the cloud top. Photo
   taken on October 3, 2021, at 11:30 a.m. local time.

   Photo details: ISO 80; f8; 1/250 second exposure.
