Glowing ball flying parrallel to the earth at about 10,000 feetWe were on the beach waiting for new year. Population of the island was about 1000 people and is a very quite island. No artificial light was observed. We were sitting facing East. The object flew in a North to South direction. At first thought it was a comet. Then realized it was traveling more like a satelite. Path was parallel to the earth at 10,000 feet. I am a pilot and feel the altitude was accurate and the speed was in excess 800 knots. No flashing anti collision lights, just a bright glow with a yellowish color. A slight trail was evident. Absolutley no sound was heard. We watched the object pass behind a cloud and reappear which gave me the impression that it was fairly close to us and not in the outer atmosphere. The clouds were scattered at 3000 feet.
