Right, first thing I'd want to know is what time this was and whether you had anything to drink beforehand - not trying to be funny, just the obvious question that'll come up when you tell anyone else about it.
The hovering detail is what gets me. Moving lights are one thing but if it genuinely held position for any length of time that rules out most conventional aircraft, especially low altitude. What kind of field is it, farmland? Because theres a documented pattern with these things appearing over agricultural land that I've been looking into for a while now, mostly tied to the crop circle stuff but not exclusively.
Did you get any feeling from it, like a physical sensation or just visual? Some people report a kind of pressure or buzzing and I'm curious whether that matches your experience or if it was purely something you saw. Also - photos or video, even bad ones are better than nothing.
