Over the ocean, you see a 'fogbow'. It is compromised of reflections of sunlights on water drops, like a rainbow, only without their loud colours. All the fog is not in this arch - as you can see by the fading hues around it - but in fact the shape is created by the water drops to divert the sunlight from the viewer from a certain angle. Because the active drops are so, so small, the wavelength of light becomes more important than the colours. Rainbows are created by larger raindrops that act like prisms, reflecting light from the sun.
I only wonder how often this happens, and if it only happens closer to water. I find this more lovely than a rainbow, and hope it happens near by sometime soon. How rare is an event like this, I wonder?
This photo was taken in California in 2008.
