My friend and i were golfing at around 1:30 pm and a shiny bright orb high in the southwest sky caught my eye through my polarized sun glasses, no jet contrails were in the sky around it and the cloud cover was about 5 percent. as we were waiting to tee off i just kept watching this silver orb go up, down, sideways, make 90 degree turns. i would say it defied the laws of gravity and physics. i used to fly a lot, so i can say this occurred at least at the height a passenger jet flies at when at cruising altitude or higher. it would stop on a dime, take off, move up, speed up, move erratically like nothing i have ever seen in my life. i kept watching it for about 3 minutes and then it was lost as the reflectivity disappeared from it. i teed off but kept looking afterward, but nothing else was seen. this is the first time i have seen something like this, and if it was not for the unexplainable maneuverability i would have said maybe just a satellite or something. i have seen satellites track at night and this was not a satellite, because it stood still, moved, and did things impossibly for a satellite to do and still stay in a confined area to perform these maneuvers. unfortunately there are no cell phones on the course so no picture or video.
