| Name | Ron D |
| Experience Level | 5/5 |
| Remarks | I am an astronomer by profession, and these details have error bars. I guarantee that the angle was within a degree of vertical (straight down) and the azimuth was estimated by distance to the left of the full moon, which I was observing at the time. |

|---|---|
| Observation | Unknown |
| Remarks | I was in a car - no sounds detected |
| Persistent train | |
|---|---|
| Observation | No |
| Duration | - |
| Length | - |
| Remarks | I could not see a train or smoke trail if there were one... it was only a few degrees from the full moon, and I was in a bright suburb of Toronto... and in a car. From the magnitude of the fireball I would expect that a train was visible but not by the moon or in a bright city. |
| Terminal flash | |
|---|---|
| Observation | Yes |
| Remarks | Smooth ramp up in brightness at end to extreme brilliance with fragments trailing, but instead of an explosion it was a huge surge, then rapid extinction to invisible |
| Fragmentation | |
|---|---|
| Observation | Yes |
| Remarks | Meteor fragmented about halfway through its flight, brightest fragment remained in the lead, and the magnitude was significant as it was. Probably 5+ spark-like yellow fragments that were constant in significant negative magnitude each, but constant until burn out. |
