    If you mean that white line, that is a a #bpc (Bad pixel column), a type of artifact from the camera taking the pixel. You will notice that the #ffd (flat field defect) artifact - the black dot - moves up between frames 1 and 2, down and right between frames 2 and 3, and back to the left between frames 3 and 4. The bpc does the same thing, only because it is an entire column of artifacts (essentially hunderds of bad pixels), moving up between frames 1 and 2 appears to keep the column in the same space. It then moves right and left in the same way that the ffd does.

    Additionally, if the line was a #fmo (fast moving object), you would only see it in one frame, not in all 4 in exactly the same alignment. Since the pictures are taken about 10 minutes apart, the chances of two fmo's crossing the images 10 minutes apart during the 30 seconds that images is being take in exactly the same location in the image is highly unlikely.
