Triangular craft observed in the sky at sunrise, moving west to east, right above the tree line.As I was getting ready for work, I had let my cat out a few minutes earlier. I heard him meow at my back door to come back in. As I opened the door I looked up and to my right (the sunrise was just starting to peak) and I saw an object traveling west to east right above the sheds in the back yard. This caught my attention because there are never planes taking this flight path, and it was low enough catch my attention, but did not emit any sound. Because of the position of my back door in reference to a barn a few yards a way, as it traveled right to left I lost sight of it as it flew over the barn next door. I think it was roughly 1,000 ft off the ground, (clearing the tree line) and the size was a little larger than a Cessna-maybe fit 4 people. There were 3 white lights positioned in a triangular shape with multiple lights inside the body. The whole event last about 10-15 seconds before it went out of my vision range. It all happened so fast, I am interested in knowing if anyone else reported a sighting that morning.
