Nice pic! Ive actually seen a few double and circular double rainbows....
Will post a couple of pics in a min... :beer:
Edit: The best double ring rainbow I have ever seen was on top of Snowdon, in Wales. It was actually made up of two complete circles! Unfortunately I didnt have a camera at that time and so I never managed to get a shot of it.
These first two were on my travels; middle of the Pacific Ocean:
This one was just after avoiding a bad +50 kt storm. The eye was + 60 kts...Dont cross in the cyclone season. Passage between Tahiti and Tonga.
The last two were taken whilst skiing in Switzerland, where lived for many years...
