Saw this object at about 11:32am today, sunday 1-12-20. the object was above a jet airliner that was flying south at approx. 2,000-2500+ feet. no clouds and could hear the jet that was going over head. the object above the jet was not an aircraft, was not a helicopter or weather balloon that i could tell. the object did not make a sound of any type that i could hear and was moving in a nw slow track from my house which puts it on a path to sky-harbor international airport in phoenix. the object was pulsating or spinning, it did not have any flashing lights like an aircraft would and could see the sun's reflection off of it as it moved/spun as if the sun was hitting an angled side as it moved. it looked diamond or orb shaped, it was somewhat hard to tell. i watched it for about 4minutes before it disappeared still moving towards sky-harbor airport. i realized i had my phone in my pocket and took a pic hoping to get a good picture and zoom in on it and see what it was. the picture is hard to tell even zoomed in, but it does not look like any aircraft i have ever seen being retired air force. hopefully, someone from mufon can tell what this is or at least an idea. i wish i would have thought to take a pic with the object and jet together, would have been a much better picture i think. attached pics are the original one and a zoomed in photo.
