For the last ten minutes I have been observing a UFO over Medway Kent Uk. At first I thought it may be a star as it wasn’t moving, but hten I noticed it changed colour from red to white to green. Came inside and got my binoculars and focused in on the object. It is a perfect circle with lights around the edge flashing randomly. The cenre of the circle is made up of less bright white lights. Been about twenty minutes since I first saw it and it is still there. It as moved very slightly from the first position it appeared in but not by much.
