Rainbow at Alesund, Norway  imaged by Patricia Hamilton on 15th July '08.

This rainbow fragment appears puzzlingly close to the horizon.

The centre of a rainbow is always directly opposite the sun. Therefore, high suns make low rainbows.

When this bow was seen the sun was 40° high placing the centre of any bow 40° below the horizon in the opposite direction. Since the primary bow's radius is about 42° that puts the bow's tip just 2° above the horizon.
