| Remarks | A brightly glowing, slightly fan-shaped trail that began to fade after the meteor grew to large and very bright white |
| Terminal flash | |
|---|---|
| Observation | Yes |
| Remarks | There was a bit of apparent fragmentation right at maximum brightness, which was a flash and sudden expansion in size, much latger than typical meteorite sighting, especially in well-lit outside area. It appeared to "blow outward" in multiple directions, but mostly upward of bright ball, but some straight down. They continued for a few seconds after fireball began to recede in brilliance. |
