My dog wanted to go out. When I opened the door she would not go off the porch. I tried to make her and when I looked up there were four huge lights equal distance from each other changing colors. They were very pretty.I thought it was plane's but there was no sound and the lights did not move from their positions. The distance between them stayed the same. There was a slight curve when it flew by the house. There were a lot of stars out but as this thing moved very slowly it blocked out the stars and we could see it was huge. My husband said it had to be miles long but it was so clear. We watched it until it was out of sight. I tried to take a picture with my I-phone but it just looks dark. It blocked out all the stars so something was there. My dog ran in the house and so did we. It seemed like it was floating very slowly. It went in the direction of the Savanna River site. We were not going to report this. I never believed in aliens coming here but I do know our military hides what they have.
