| Experience Level | 3/5 |
| Remarks | we thought it was lightning at first as my husband saw the BRIGHT flash in the top window of our front room and I saw the reflection of the flash on the blinds, my back was to the windows; went outside and that's when we heard what we at first thought was thunder, but as the rumbling continued, realized it was not thunder. Neighbours also saw the object and heard the rumble and all were exclaiming "WHAT was that!?!?!?!" |
