Round, dark disk shaped object with lights all around it softly whirred by, hovering overhead for a few moments and then moved on.

Me, my sister, and our best friend were lying on a blanket on a late Spring night in 1962.  I was about 11 years old, my sister would have been 10, and our friend would have been 9.  
We were "star gazing," looking up at the beautiful night sky.  Suddenly, a round dark object with lights all around it (I think they were clear lights, but they might have been colored...I don't remember) came softly whirring by.  
It seemed to hover over us for a few seconds, and then whirred on into the night.  I don't remember if it came back or not, it might have. 
I have never spoken about this incident before today, but when I watched a fascinating program on Larry King Live/CNN last night I realized that other people have had these same experiences, so now I don't feel alone.
((NUFOR Note:  Witness indicates that the date of the incident is approximate.  PD))
