| Name | Scott M |
| Experience Level | 1/5 |
| Remarks | I was sitting in a room, watching tv, when something outside caught my attention (through the window). When I looked I saw a light blue object, with a blue trail behind it. It lasted 3-4 seconds, then disappeared. It seemed large and close. Not like a shooting star high up and small. I've never seen anything like it. I expected to hear a sound as it appeared to be close, but I heard nothing. |
