It was 3:45 am and I was outside looking at the stars. I happened to notice a satellite moving fast above my house then directly behind it a very large triangle shaped object moving quickly, with no sound and no vibration. I did not see any defined shape except three glowing lights that were definitely not stars, and the object changed direction and moved the opposite way above my house. The entire event was over in about 30 seconds. I stared up at the sky for another half hour after, losing sight of it because of all the trees in my yard and surrounding area. At first I was unsure of what I was seeing, then the second time it went over the house I knew exactly what it was, and the fact there was no sound and how fast it moved. I got very excited, but I think I may have gone into a slight trance watching it move overhead. It was there and then it just sort of vanished, like the lights were bright and then they went dim the second time it went by.
