At around 11 oclock at night we my wife took the dog out to the front yard. She then called to me to come out andf I saw an arch of orange lights.There were about 6 or 7 lights that seemed to pulsate. This arch was huge and silent. Then they started to change from orange to white and disappeared from the left bottom to the right. When they all disappeared I saw another which appeared bigger coming fron the east and then taking it place in what was an arch. My wife and I have worked on military bases for over 17 years and we know the characteristcs of flares and chaff. This was neither. I do feel different after seeing this.
