This report has been linked to the following event: Event 7139-2021
Observer
NameMike M
Experience Level2/5
RemarksI was northbound on an ascending road, curving from northwest to northeast. Since I was looking upward while below the top of the hill, there was nothing obstructing my view, and glow from the city lights was blocked. The entire trail and flash at the end were well above the elevation where I have seen commercial fireworks. The nearly vertical trail and flash ruled out it being an aircraft.
