| Name | Tammy Y |
| Experience Level | 1/5 |
| Remarks | It was a streak of light green, glowing light, cylindrical object (dark interior/green flow around the exterior) flying perfectly horizontal. There was no angle to it's flight - that's what made me think it couldn't have been a firework. Perfect horizontal flight. It was flying north/south. I was viewing it facing west. I have seen comets before - this was NOT like that. No big long tail behind it. |

| Observation | Yes |
| Remarks | I saw one piece (circular - dark interior - outer edges orange) break off or leave the main green object (it was behind and went UP slightly from the green object) - the orange faded and the dark pc fell away - I don't recall what happened to it - I did not see it go down - just disappeared - that could have been when I started messing with my phone to get a picture. Didn't get the picture. |
