Reports Report 5311bo (Event 5311-2017)

Observer
Name Kelly F
Experience Level 3/5
Remarks I thought it was just a weird green meteor until the enormous (in comparison to the wider-than-usual streak) white burst. I watch the August 12 shower most years, and I've seen several meteors in the past 40 years, but nothing this big, or pure white (or with a green streak). If I didn't say earlier, there was the green streak, wider in the middle than the ends; 2 or 3 very brief yellow flashes (not bright); and then the white pulse that lasted a full second, dimming slightly once halfway through, then brightening again.
