Orb of light Observed

At approximately 2:30am whilst out lamping rabbits in a very rural location near my home I witnessed a very bright orb of light travelling silently from east to west almost directly above me.  The light was approximately 1500 feet from the ground.  I observed the light through my 3-9X40 rifle scope.  The orb did not seem particularly defined but it did emmit a very clean,bright white light that I would describe as dazzling.  The orb was not moving very fast and I was able to watch it for several minutes as it passed over the field i was in. The Orb headed over a wooded area to the south west of me and then stopped dead, then a small pinpoint of light broke away from it and proceded to dance erratically around the orb performing manouvers that I would imagine any conventional aircraft would find impossible. This carried on for several minutes until the pinpoint dissappeared.  The larger orb remained stationary as I began to walk home with my back to it. I then lost sight of it through the trees.
