Watering plants in my backyard when I heard jet fighter(s) in sky. While attempting to see them observed a strange white/silver object in the distant sw sky. Called my wife out and we both watched it for about five minutes or so while it remained stationary. The object then slowly moved to the nw and faded from view in another five minutes or so. Just thought it was another UFO since living out here in the desert and sitting outside often at night we have seen objects before.
