Reports Report 200g (Event 200-2016)

Observer
Name Deanna R
Experience Level 2/5
Remarks Saw other people comment about it online (Facebook & Twitter) around the same time, and people in Illinois on Twitter- "swore it entered the atmosphere". I would love to know what this was, & where! I was looking at the moon when I saw what I at first assumed was an airplane. Then it dropped almost vertically into the horizon and got massively bright.
