Orange/red ball of light heading from S to the N the appearing to stop and change course leaving the atmosphere.Me and my fiance were sitting outside when a ball of light appeared from the south at the treeline heading north faster then anything I've ever seen in the sky. During its path, the object changed color from orange to red constantly until it appeared to stop its northern progress and move away from the earth.It then appeared to start slowly fading in and out until it appeared to leave the atmosphere.No sound was heard by either of us from the object; it was too far away, I'm assuming.
