Yellow Icon – location of object at midpoint of reentry window
Orange Line – area of visibility at the predicted reentry time for a ground observer  -- area of potential visibility if the reentry occurred at the middle of the window
Blue Line – ground track uncertainty prior to middle of the reentry window (ticks at 5-minute intervals)
Yellow Line – ground track uncertainty after middle of the reentry window (ticks at 5-minute intervals)
White Line – day/night divider at middle of the reentry window (Sun location shown by White Icon; lighting shown at the center of the window)
Pink Icon – vicinity of eyewitness sighting

Note: Possible reentry locations lie anywhere along the blue and yellow ground track.  Areas not under the line are not exposed to the debris
