Best Answer
The centre of a rainbow is where your shadow would fall. When you're standing on level ground your shadow is obviously on the ground so you only see part of the arc. If you're in an aeroplane or on a mountaintop or somewhere where your shadow would be above ground, you may be able to see the whole circle.
