While I still don’t know what the orb like objects are, I know reasonably sure what they’re not. What they’re not is the Stratellite communications balloons. Those are equipped with GPS and station keeping propulsion so they stay in one place to provide communications services.
I photographed the same area the orb was last present today when that portion of the sky was clear, no orbs, or much else of interest. If those had been a Stratellite device, it would have still been there.
