Just before the above time I chased a fox off the plot. Came into the porch to remove muddy boots. Had my light on the iPhone. I Looked up and saw a white dot traveling at a extremely fast speed from West to East. Faster than I have seen any aircraft travel. No Nav lights visible just a white dot. This was almost vertical above my head. I could not estimate distance but certainly very high. It stopped above me and vanished. assumed vertically. I have it on iPhone doing a half circle before disappearing. The phone/Camera is still. Doing stills of video to send.
