Sorry for you Tinstaffl that you have not yet seen the real thing.
The full circle rainbows Global Pilot and I have seen only form in rain showers. They retreat from you so that you never get close.
And they are huge. Not the ones that you often see on clouds.
Can you imagine Global Pilot going into raptures over your tiny ones.?. Hope you see the real thing sometime.
Just asked another pilot with a lifetime of flying behind him and he confessed to never having seen the big circle. Must be more rare than I thought.
Perhaps there are some observations of the full or nearly full circle when viewed from a mountain top.
