| Delayed Sound | |
|---|---|
| Observation | Yes |
| Remarks | Both of us heard a faint sonic boom or deep explosion sound (just like aircraft sonic boom but much quieter) roughly 3 minutes after the sighting, followed by a roughly 20 second delay, then 3 more booms in a 2 second period, then at least one shortly after (total duration of booms about 30 seconds). We live in very quiet rural area 1.5 miles from road and cool evening meant quieter bugs/frogs or we would not have heard it. Each boom was short, roughly 1/2-3/4 second in length, similar to distant gunfire but much deeper and less echoic, like a very deep popping sound. No fireworks in vicinity, so no doubt in my mind that these were from the fireball. Last of the booms was/were quieter than the first four. Neighbor's dog started barking immediately after the first boom. |

| Remarks | - |
| Terminal flash | |
|---|---|
| Observation | Yes |
| Remarks | One of the smaller fragments flashed a few degrees past zenith, but I cannot say with certainty that it disappeared after that flash. |
| Fragmentation | |
|---|---|
| Observation | Yes |
| Remarks | I did not see the fragments actually break off from a central body, but I did see at least 4 distinct bodies travelling together. Not sure if this question is asking if I saw the physical act of fragmentation or the results of fragmentation (fragments). |
