| Experience Level | 3/5 |
| Remarks | This object was very bright, lasted a long time and the explosion was very obvious. I can't believe more people haven't reported it. Even though it was the middle of the night, I felt like it could have been seen by the whole west coast. I started google-ing for videos as soon as I got home. |
