In my opinion one of the best photos I have seen on UKC for quite a while.
Brilliant work!

Why is it upside down? The Rainbow that is...

Sean - The "upside down rainbow" `Circumzenithal` CZA arc is an etherenal rainbow fled from its watery origins and wrapped improbably around the zenith. The CZA forms only when the sun is less than 32.3 deg high. When the sun is near the upper limit the arc is faint, as the sun sinks the CZA brightens, extends into an arc of increasing radius and becomes narrower. It is at its best when the sun is about 22 deg high ! NIce photo :)

Nice photo - There an excellent page on CZA and other atmospheric optics at which explains how they are formed.

I would rather say it's a CIRCUMHORIZON arc (or may be INFRALATERAL arc), it seems like the sun is higher than 58 deg!!!
