Low and High Rainbow

Here I have combined two shots from yesterday of two different rainbows. It's interesting to see how the Suns altitude in the sky affects the height of the rainbow.

The first photo was taken at 15:25 UTC (Add two hours for Swedish summer time) when the Sun had an altitude of 27° above the horizon. In the second shot, taken at 19:48 UTC, the Sun was just 0.033° (2 arc minutes) above the horizon. At sunrise or sunset a rainbow's centre is on the horizon as seen in the second image.
