| Name | Tiyena K |
| Experience Level | 3/5 |
| Remarks | A blue in appearance lightening flash went off out my window, which originally drew my attention, then almost instantly I saw a red and orange fire ball just above the tree line that either disappeared from sight or fizzled out very quickly. The boom was thunderous and rumbling and came 1-3 minutes afterwards. |
