| Name | Julia R |
| Experience Level | 1/5 |
| Remarks | The light coming from it was not uniform. It was as if there were rays or streaks of this darker green/slightly blue light. My very first thought was of fireworks, but this object had to be larger (from my perspective) and I was seeing it from rather far away. It got a bit brighter and then fizzled. If I had to guess, I would say that it was located somewhere south of Chicago, possibly Eastern Central Illinois. |
