This is circumzenithal arc a bit like an upside down rainbow. II've seen one a couple of times before but this is the first time I've managed to photograph one. More info here https://en.m.wikipedia.org/wiki/Circumzenithal_arc
you're rather lucky to have captured such an interesting phenomenon, richard. i've seen it once here but that was pre-365 so all i did was stare at it with my mouth open, wondering if the earth was going to explode any minute then. aces on this capture!
