| Name | Jonathan H |
| Experience Level | 2/5 |
| Remarks | My honest beliefs is that this was a UFO, as when it disappeared it shot slightly upwards. about 15-20 minutes after i saw this with two of my friends, a red light (probably a helicopter) was flying around the area, and wherever it was, you would hear small explosions and booms. |
