Reports Report 4829g (Event 4829-2017)
| Observer | |
|---|---|
| Name | Mike A |
| Experience Level | 3/5 |
| Remarks | I was driving, and so I probably wouldn't have heard any sound (the radio was on). The time is approximate. It would have been between 8:55 and 9:10; I didn't note the exact time. Nevertheless, visually, it was hard to ignore, despite a lot of brightness (from the headlamps of oncoming traffic), buildings, etc. It may have been around for less than a second, but is was visible for what seemed to be slightly longer than a second. Somewhere between 0.5 and 1.5 seconds would be my best guess. |
