Reports Report 2717l (Event 2717-2017)

Observer
Name Claire B
Experience Level 2/5
Remarks I started by facing away from it, talking to my brother. Suddenly I saw shadows on him as if a flashlight was shining on him. I turned around just in time to see a bright light about half-ish the size of the moon disappear under the mountains. It was pretty low but the trajectory could have been longer had my view not been hidden behind a mountain range. I was at 7,500ft elevation.
