How About a Yellow Flash?

I have posted a lot of pics of green flashes at Sunset (just enter green flash in the search box and you can find out all about them). However, not all flashes at sunset are green. I have photographed blue and purple flashes as well.  Tonight, I added another color to the mix.

First, it was a nice omega sunset again.  Here are a couple of shots.

The omega sunset occurs when an inferior mirage of the Sun appears to rise up from the horizon to meet the setting Sun. Hence, the resulting shape looks like the greek letter Ω.

Tonight the last little bit of the Sun set leaving behind the very tip of the inferior mirage and it was yellow.  You can see this is not connected to the main image of the Sun. Sometimes these flashes are green, tonight I got a yellow flash.

Always watch, you never know what you are going to get!
