An object that was just above the trees, hovering and taking off in a split second, out of sight.

My husband and I were talking one night, and I saw a bright light out of my window, looked out and there it was, hovering over the trees. 
I could see it had an almost octagon shape and there were lights surrounding the craft. We were both stunned, just staring at waiting for it to do something. Before we knew it, it went straight up out of sight. 
We kept staring out the window in disbelief, then all of a sudden it came back just as quickly as it left. It didn't make any noise that we could hear, but it continued to leave and come back five times.
Witness indicates that the date of the incident is approximate.  PD
