Marie took this picture during the week of March 23rd to 28th 1992, while she was having her vacations in Cabarete, Dominican Republic.
She took pictures with a Nikon 35 mm and never noticed the object in the clouds at the right of the picture. She just noticed this object lately while she was scanning this picture for another project.
She took other pictures the same day which do not show any thing like that, so this is not a dust on the lens.
What do you think of that object? Is this what we can call a “Serpent sky”? Or “Quetzalcoalt” appearing close to equinox time?
