Saw this strange object floating in the totally clear sky on 23rd August at 19:40 whilst on a coach. It was totally still, and very bright. These are all the videos I took (live photos), and then the same clips zoomed in, and a still shot at the end. I’ve tried to look in the area on Google street view since taking these and I can’t seem to see anything. Is anyone familiar with a balloon that looks like this? I’m not sure what it is.
