Boomerang shaped black body, green lights motionless and silent. Vanished after I came closer to it.While walking home at night the sky was very clear due to the cold weather. The night sky was inky purple. I observed a boomerang shaped object the perimeter of which was dotted with green lights. My hometown was very small and quiet. I heard no noise whatsoever. I continued to observe the object and found myself actually running towards it to get a better look. Once I was out from underneath the street light I was in a position to see it better I held my breath so the water vapor would not obstruct my view. The object remained totally motionless. I estimate it was 500 to 1,000 feet from the ground. I watched it for about a minute and the green "marker" lights on the outer edges went out starting with the "lead" light than the #1 port side, #2, #3 etc... until the last light on the starboard site turned off and the object was gone. This was the one and only "unexplainable" thing I've seen first hand.((NUFORC Note: Source of report indicates that the date of the incident is approximate. PD))
