Reports Report 241a (Event 241-2011)

Observer
Name Kenyon
Experience Level 3/5
Remarks It was still daylight, just minutes before sunset; the time of day when your shadow is just blending into the first shadows of evening, but the sky, trees, and buildings are still brightly lit by the sun. I was at the park with my dog, and a number of other dog owners. We were in a circle talking when I spotted the meteor, and it lasted long enough for everyone to turn, find it, and observe it for several seconds. I estimate it was at least four, and possibly closer to six seconds--but I wasn\'t exactly counting (I retraced it\'s path and approximate speed to figure this out immediately after).

Observation Yes
Duration 1s
Length 3.5°
Remarks light gray/white smoky color, dissapeared quickly. Just as I lost sight of the meteor it appeared to break up, but I can\'t be sure on that; at the last second several short trains appeared for an extremely brief instant and then vanished with the rest of the main train.
Terminal flash
Observation Unknown
Remarks The meteor disappeared in the vicinity of several hi rise buildings that were a few blocks distant. I thought I saw fragmentation, but can\'t be sure--only saw the train \'split\', and the main body dimmed and went behind the building assuming it wasn\'t completely vaporized. I saw no terminal flash before it dimmed, but it was very close to going behind some buildings and I can\'t be sure something didn\'t happen out of my sight.
Fragmentation
Observation Unknown
