My age was 8 at the time and I was in bed just starting to fall asleep. Mother was in the den calling me to come "see something". I did not respond so she got me out of bed to show me this object in the sky throgh the den window. When she pointed at this object with her eyes and mouth wide open it had almost a hypnotic effect on you. Estimates on it's size are difficult but the main feature of this object was the different colors that consistenly evolved around it. There was red white yellow and i believe blue as well.I have two semi different recollections in terms of the shape of the object. One being flat as a pancake and the other changing as a larger craft as the evolving lights became larger. The movements of the lights could be compared to a light house or even a siren. We wathched the object for at least 15 minutes in complete amazment
