One year I was in Quartzite, Arizona at a lapidary show.
I was having a beer and sitting outside our mhome looking at the sky with my binoculars for fun (stargazing).
Out of the darkness, I saw almost the same thing, but in my case, the light changed direction immediately and looked like it "bounced". It changed direction with NO curve, just an instant right turn. I was blown away. There were no physics that could explain this so far up in the sky. It did not look like a bounce as much as an instant turn with a perfect 90 degree angle.
