One night while making a timelapse of the stars I caught a meteor that left a persistent ion train, lasting about an hour total. This is a timelapse so that hour is compressed into about 7 seconds. Watch the bottom of the sky slightly to the right of the center. The ion train turns from a straight line to an S shape and then it blows out into a bubble that expands off the top of the frame. There's an airplane or meteor that streaks from the bottom to the top of the frame and by the time it exits at the top, the ion train is gone.
This is difficult to see, and may take you more than one viewing to catch it. I'm working to produce an enhanced version.
