An orange ball shaped object suddenly arose in west, changed to a rectangle going east, light began pulsating before it disappeared.An object suddenly but slowly rose up in the western sky above the trees very close to where we were standing. It then began traveling east right across our sight line. It changed shape from a ball to a rectangular shape and the color shifted from orange to white. It was completely silent. After it crossed in front of us, the light began to pulsate several times. Our view was then partially blocked by some tree branches as it continued to pulsate and then never reappeared from behind the tree branches as expected. It just completely vanished as if it slipped behind some clouds but the sky was completely clear at the time.
