This report has been linked to the following event: Event 3837-2017
Observer
NameDan V
Experience Level3/5
RemarksI was driving in my car, and coming around the traffic circle, and I saw the fireball as I was about halfway through the circle to my exit... It was very brief but I happened to be looking at just the right direction and so could not miss above the trees/buildings that were directly in front of me/my car. I asked if anyone else saw it on Facebook but nobody has so far.
