Reports Report 2318b (Event 2318-2017)

Observer
Name David W
Experience Level 2/5
Remarks I didn't see it in my field of vision until it suddenly flashed brightly and appeared larger than any star or planet, not quite as large and bright as the full moon; lasted 1-2 seconds, it had a short but bright tail from above it but both the tail seemed to disappear as soon as the flash ended. While it flashed it appeared to be falling downwards rather than going across the sky. I've watched meteor showers before and have seen "shooting stars" but I think this is the first fireball I've ever seen. It was surprisingly bright and large, so I almost expected to hear an impact, but it was likely much farther away than it appeared to be.
