Chevron shape hovering in place

On January 4th at 9:19 I was outside smoking a cigarette. I noticed a large chevron shape hovering in one spot. It had lights running along the outer edge and at times appeared to move from left to right.  I see low flying air craft all the time and have never seen something so large at this elevation. The object dropped lower and I went to my back yard to film some more and by the time I got there it was gone. I took the footage and zoomed in and you can tell there’s a cylindrical vase like structure sitting inside the chevron shape with a hole in the center. The object at time can be seen emitting a tail from the center at times in the video and the lights appear to also pulse brighter and softer at times. I have more footage if interested.
