I have a week bladder, and I happen to have a door from my bedroom going outside, so I go out and pee every 2 hours or so. I always look at the stars, sometimes for 5 minutes or more at a crack. I spotted a dim red light moving north to south. It was fading in and out, and I was trying to relocate it when right over my house a triangular thing flew from east to west. The lights were slightly dim but seeable. That’s why I think it was outside the atmosphere. It was about the size of say a full moon. It was moving very fast.
