| Name | joseph a |
| Experience Level | 2/5 |
| Remarks | i was fishing and facing the south. As i turned to the north, i caught the tail end of the event and did not know what i had seen, so i checked my watch and recorded the time. From my vantage point, the fireball appeared quite large with a firey tail. after it descended below the hills to the north, i saw a large explosion and i think i actually heard it as well. everything appeared to be quite close to me. it was quite an amazing sight |
