I was cresting the Arbuckles on I-35 last night when I saw it. Started out as a lumiescent green light making me think it was a low flying aircraft at first. As it tracked eastward a tail developed and smaller flares of light broke off. The tail grew longer as it seemed to slow and change to a yellow/white color. Finally it sputtered out leaving a trail of sparks behind. It was cool to watch. It's the second one I've seen in three weeks.
