I was at Copper Ridge Elementary school in N. Scottsdale for a men's soccer game. I arrived at ~6:45 and proceeded to the edge of the fields to relieve myself. I looked up and saw a massive cigar shaped object that was glowing gold/orange then within a few seconds the object which appeared stationary the entire time just vanished. I must have been at least 20 miles away from this object which appeared to be several thousand feet above the NW horizon from my vantage point. I only saw the object for a moment but I know it was not any conventional aircraft. When the object "blinked" off and vanished I was instantly amazed at how something so big could just disappear instantly from my site.
