I was on the front porch of my home facing west looking at the stars when I heard a quiet "whooshing" sound, As I started to turn to look south where the sound was coming from I observed a very bright light moving perfectly horizontal east to west at a moderate to fast speed. I felt scared of what I had just seen so I told my wife about it and she went out side to see if she could see anything, all she observed was what appeared to be a smoke trail. I lost sight of the object when it disappeared, it did not fade it just disappeared.
