Reports Report 451hi (Event 451-2015)

Observer
Name Suzanne M
Experience Level 3/5
Remarks One of the most amazing things I've ever seen... slow-moving, (seemingly) low-altitude, on such a perfect, crystal-clear night. I thought someone had set off a firework when I first saw it, but then I realized it wasn't moving up, it was moving across the sky. We immediately pulled over and I was able to watch it cross directly overhead through the moon roof of our car.
