UFO Sighting in Bridgton, Maine on June 17th 2015 – White orb, brighter and bigger than a star, flies straight, changes direction then disappears

My husband and I were taking our dog for a walk through Bridgton. As we entered the parking lot of the movie theater we noticed a large moving orb in the sky, it was bigger and brighter than any star in the sky. It was moving diagonally from the horizon, and when it was about 6 inches above the horizon it changed direction and began moving horizontally, parallel to the treetops. It moved faster at this point, slowly turned yellow/orange and grew smaller and smaller until it disappeared. This is not the first time we have seen a craft of this type, we have seen these multiple times before; sometimes in pairs, or moving/changing direction more dramatically.
