Orb hovers for more than an hour

I was golfong at Rio Hondo golf course.  Our tee time was 9:30.  While walking to the second tee I looked up into the sky because the course is in the airports flight path.  While looking up( about 75 degrees upward) and facing North, I noticed a shiny orb in the sky.  I told my friend, who had a hard time seeing it without polarized sunglasses.  As I continued to look around, another one appeared higher and to the left of the first.  And finally a third appear almost directly overhead.  The second and third one stayed for about 10 minutes.  However, the first one I spotted stayed within visual range (never moving from its relative position) for more than an hour.
