On a clear night you could see the saucer

It was a very clear summer night in 1965.  I was ten years old and was sitting outside with my parents, our neighbors and their daughter who was about seven years old at the time.  There was a full moon and my dad said, "What is that object that looks like it is coming from the moon?"  
We all looked up to where he was pointing and there is was, up very high in the sky, a disk shape with colored lights around it.  The lights were blues, reds and a strange glowing green color.  
As we all watched this craft, it stayed in the same spot in the sky but the lights moved on the craft in a round about motion.  The adults discussed what it might be and any kind of air craft of the date/time was ruled out.  No air plane no blimp, no helicopter.  You could not hear any sounds coming from the craft most likely due to the distance that it was from us.  
Although, it was as if we watched the craft for no longer than a five minute period, when the craft finally moved it took off very quickly flying to the left and disappeared like it had never been there.  When the adults checked the time, it was as if a whole hour had gone by that no one could account for.  
The neighbors left for home my family went to bed and this incident was never discussed again.  I asked my mother about it many times after it happened and she kept saying she did not know what I was taking about.  It was so strange the way everyone acted afterwards. 
I do have a small scar area on my upper arm I did not have before that night.  Not painful and not sure how I got it.
Witness indicates that the date of the sighting is approximate.  PD
