Remarques | It looked almost like a singular firework star, which I assumed it was at first, but then I realized the velocity was much too fast to be a firework, and the trajectory too straight. It looked rather large, maybe half the size of the more widely reported cases, despite the absence of any sounds. |

Observation | Yes |
Remarques | It was less of a flash and more of a ramp-up to a maximum magnitude. The streak began as white/yellow, intensified as it moved across, and as the magnitude neared maximum before going out, I could see tinges of green outlining the white center. |
