I saw a bright-white orb appear (clear sky), travel 5 sec.parallel to the east coastline heading N, then disappear.

It was the early morning hours of September 13th, and the last day of a three day meteor shower.  I often enjoy these events and didn’t want to miss the last morning of the event.  I got up and went outside with a pillow to lie down on our bench to get a good general view of the sky before the sunrise.  My feet were facing south, my left shoulder to the east coast (the sun was beginning to rise a bit).
I caught the first meteor in the upper right quadrant of view…. It was orange in color and zipped the usual speed (1/4-1/2 second in length).  A few minutes later I saw the second…in the bottom left quadrant….same seed.  It was bright white in color.  I then noticed an airplane…flashing lights in the right, middle area of my general sight.  It was going the usual speed….and quite a bit slower in speed as the meteors….I do not recall if I heard it.
Then (at the same time as the plane was flying from right to left in the middle of my vision), all of a sudden a white orb appeared to the left of mid-field.... out of nowhere.  It was a circle/ball of light….opaque in substance as best as I could tell with my eyes.  There were no clouds in the sky (except a long thin one that was at the bottom of my field of sight).  The orb was quite a bit larger than the meteors…..about the size of a red light when you are stopped about 4 cars back.  Best I could tell it was way over the tree line but below the height of the airplane.  It traveled south to north for about 5 full seconds and then just disappeared.  It was traveling at least 4 times as fast as the airplane, but at least 4 times slower than the meteors.  It didn’t waver; there was no sound; no pulsing; it followed a straight line….and just…was gone.  I have never seen anything like it and I am an avid sky-watcher.  Whatever it was…it seemed to follow the coastline.
