    I'm not sure what this green line represents. It looks very similar to a lazer.

    It's a satellite trail (so you should classify it as artifact)
    The fast movement of the satellite together with the sun reflecting on it causes the camera to capture it in just one filter
    Such trails can be red, blue as well as green of course.
