Once I saw both one of those and a regular rainbow at the same time while riding my motorcycle back from Colorado. The sky was mostly clear, but there was one cloud that rain was falling from off to the east, in its rain I saw the rainbow. Above me, but partially obscured by the uppermost part of the rain cloud, was the circumzenithal arc, or upside-down rainbow as I called it. I wish I had a camera with me when I saw it.
