Observed five red lights spinning counter-clockwise,it moved slowly left hovered and and then moved back to the right into the wood li

While sitting on steps a friend and I noticed a circular object with five red lights and it slowly moving while the lights moved in circular motion I beleive counter-clockwise. The object came across the tree tops to a hover over a field stopped for few min. maybe 3-4min. and then moved back to the right.  
To this day their is definitely a round indentation on the ground burn marks only on the bottom of a few old fence post nearby. 
The weather that nite was clear warm an sky was full of stars observed this appx. 500-600 yards away.
Date may be approximate, although the witness does not indicate that fact.  PD
