We spotted a silver shiny orb like object at or above cloud cover height in an otherwise clear sky. It was heading on an easterly course in the opposite direction to the wind direction so appeared to be acting on its own propulsion. I checked on my aircraft app and there was no aircraft in that area at that time. I have video footage from my IPhone of this which is 3 minutes long. The object was round orb type and appeared to be silver with sunlight shining off it. There was one object. I am a semi retired ex Supermarket manager and my wife is a part time primary teacher.
