This report has been linked to the following event: Event 994-2016
Observer
NameNeil B
Experience Level5/5
RemarksI did not witness the actual meteor in the sky, so the angle data I have submitted is estimated from the shadows and light I saw. I was sitting in a car and saw the ground/sky light up, but I immediately knew what was happening and tried to absorb as much data as possible for reporting and logging. This was not an average meteor/bolide - it was large and close and there is a good possibility of fragments having reached the earth. I would have been getting out of the car at the estimated time of a shock wave impact, so if there was a noticeable shock wave associated, I did not feel it.

Remarks-
Delayed Sound
ObservationUnknown
RemarksA loud, distant boom, much like very powerful distant thunder. An almost rumble, with a distinct sound of 1 larger explosion followed by at least 1 softer explosion, followed by an echo. From the time the ground lit up to the time I heard the sound was approximately 50 seconds. It was an unforgettable sound and an unforgettable sight.

Remarks-
Terminal flash
ObservationYes
RemarksI didn't see the actual meteor in the sky. I was sitting in a car and the entire ground lit up so bright that I had to squint. It faded bright and then flashed extremely bright, which faded out and flickered from very bright to extremely bright until it faded away. I've seen thousands of meteors and many bolides, but this one was extremely large and close. The entire visible flashing event lasted approximately 3-5 seconds.
Fragmentation
ObservationNo
