The sun setting into fog, as photographed by Paul Brewer.

We have fog over the Pacific Ocean today so this scene might be repeated tonight. Paul Brewer photographed this recently.

It looks like it was going to be a green flash. You look for the top of the sun to separate, giving you a short, emerald green flash. It rarely happens, though, setting into fog, but I have seen it once or twice.

Thanks to Paul for allowing me to share his photo with you here. To see more of Paul's nature photography, here is his website: http://www.capturingnatureswonders.com/
