this was a relatively short sighting from my vantage point because I didn't notice it until it was out in front and high in the sky above my car as I was driving northerly direction. so it may have been a longer sighting for others who may have seen it outside of their car, perhaps walking.

as the bright green faded, it ended with what looked like red-orange sparks (fragmented), I was driving northward so I couldn't hear it from my car. At 8:50pm it was twilight and yet the meteor appeared quite bright.
