| Name | John H |
| Experience Level | 2/5 |
| Remarks | At first, I thought someone was shining an extremely bright light, like a laser in my eye from outside my window. Seriously startled me. I grabbed a flashlight to investigate outside my window, back yard, side of the house, and front yard. When I returned, I heard a loud boom, like an explosion. I did not know what it was until I watched the local nightly news on August 27, 2023. |
