Dave Murline hoists the “Day Shapes”. The shapes and sequence of “ball, diamond, ball” are hoisted when we are towing equipment at slow speeds and cannot maneuver very well.

At night, the shapes are replaced by a “red, white, red” sequence of lights that means the same. One of the satellite antennas domes is behind Dave.
