| Observer | |
|---|---|
| Name | Adam B |
| Experience Level | 4/5 |
| Remarks | Immediately after observation I pulled out my smartphone and noted the time. Together with another observer (Sarah Pallo, 602-300-1563), we determined the location of the fireball compared the night sky. The observation started in the vicinity of Castor and moved diagonally to Kocab before fragmenting into 4-5 pieces, finally disappearing behind trees below 10 degrees in altitude. |
