The arc you see is a part of a circle. Notice that as you move, the rainbow appears to move. If you go up in elevation you see more of the circle. Go up high enough and you see a complete circle. You can create your own rainbow at noon and see a complete circle. When the sun is high overhead spray a mist around you. You should be able to create a "hula hoop" rainbow that goes around your body. This can be seen naturally in when standing in heavy mist blowing out from the base of a waterfall.
