Mini rainbow?

As we were having dinner we noticed what looked like a mini rainbow in the sky (look to the right of the sun). I have no idea what that is or how they come about. It was a lovely dry evening but he clouds were building up. Any ideas?

Another day spent in Watergate Bay. I spent the afternoon surfing in what apparently was the best conditions in months down here. Fantastic fun - and made me remember how much I enjoy trying to surf. At least this time I got up more often than not and stayed standing too!

This evening I ate my weight in food at Fifteen. Fantastic as always. Now watching the last few surfers from the balcony of our room.
