I dare say that all those of you out sailing today will have noticed that the visibility was suboptimal. We didn't go out but I popped down to the boat briefly and then we called by in Walton to see if the sea was still there; it wasn't. Just before I got into the car again I looked over my shoulder and saw this fogbow, the first I have seen for a few years. There is a faint tinge of colour in a fogbow, which is interesting because it is cause by diffraction, unlike a rainbow.
