| Name | Gabriel M |
| Experience Level | 2/5 |
| Remarks | Originally I thought that it was a firework like a green Roman candle that somebody had shot off. But it was flying so perfectly horizontal, going South to North without breaking apart, that I knew that it wasn’t a firework. It appeared almost out of nowhere like a green fireball and just sailed across the sky. |

| Remarks | It appeared to have little flares stray off behind it twice when I saw it. It almost looked like some of the light from the meteor melted off behind the main body. |
