Rectangle object with three circular dim red lights.On April 17, 2012, I was standing in my backyard looking up at Mars and the constellation Leo. It was a clear night and no moon light, when an object flew into my vision. It was very dark with three red lights on the bottom. It was rectangle in shape and I could see very dim white lights at the top of the rectangle. I could tell that I was not seeing the whole object. There were no beacon lights and the object did not make a sound. If I hadn’t been looking up, it would have flown of my head without me knowing. The three red lights on the bottom of this object were circular with a red dot in the center. (Like a target). It was traveling at 40 to 45 mph and was no higher than 150 to 200 feet in the air.
