Fogbow

I observed a fogbow this morning. A fogbow is essentially a rainbow, but the drops of water are so small diffraction robs it of color. The camera did not do it justice, the bow was an obvious white arc in the sky. Unsharp masking helps to make it visible. Note the dark edge inside it, this is part of a supernumerary.

Another dewbow!

I saw another dewbow this morning, it was much better than my previous observation. It was much brighter than in the picture, and showed very well as you moved, very obvious.
See the faint arc?

Tiny Dew Bow

I observed a small dew bow in a spider web connecting a few blades of grass. Standing up, it showed bits of color as you moved your head.

Unfocused image, if the image is focused it
is practically invisible.

Heavily unfocused, see the colors?
