Could this object, from a Wired Magazine article on Stratellite’s be what I photographed? These are spherical lighter than air ship designed to remain stationary at a location 13 miles high in the stratosphere to provide communications.
Seen in the daytime they are white and so would reflect the color of the surrounding sky. They should appear fuzzy though like the objects my photographs (and that is a property of the object because other items in the same photo are clear).
