An extremly bright, sporadically moving object seen flying then slowly fading into nothing before our eyes.

On Monday night June 8 at about 22:43hrs, There was a super bright light roughly as high as a cruising jetliner (30,000 ft or so). It caught my attention because one...it was BRIGHT! It was brighter than any light on a plane that I have ever seen.  Two, the entire object looked spherical and unlike a plane or helicopter of any kind.  Lastly, the way and direction it was traveling was odd. It was moving fairly slow, but somewhat sporadically.  It also changed direction rather quickly with no wide turns like a plane or anything like that.
Another thing that caught my attention was the direction of travel. I live somewhat close to LAX Airport and often watch the planes lined up for miles on their decent. Rarely do I see aircraft headed at a 90 degree angle towards the line of planes. It was a good deal higher than the planes on their way in for a landing and was of no threat to them. But again, I do not see aircraft flying in that direction.
After watching the craft for roughly a minute or two it seemed to start moving higher up and away from us. The once extremely bright sphere began to slowly fade away right before our eyes until it was completely gone!  There were no clouds in the sky at the time and no obstruction of our view.  It simply vanished into nothing.
