Explanation: What is that white arch over the water? What is being seen is a fogbow, a reflection of sunlight by water drops similar to a rainbow but without the colors. The fog itself is not confined to an arch -- the fog is mostly transparent but relatively uniform. The fogbow shape is created by those drops with the best angle to divert sunlight to the observer. The fogbow's relative lack of colors are caused by the relatively smaller water drops. The drops active above are so small that the quantum mechanical wavelength of light becomes important and smears out colors that would be created by larger rainbow water drops acting like small prisms reflecting sunlight. The above striking image of a fogbow was taken last week with the Sun behind the photographer. The rocks in the foreground are part of Ocean Beach in California, USA.
could you add me to the ping list? Thnx.
hum....I know he said it didn’t have colors and it may be my imagination, but I swear I see some pink on the outer edges....
Very unique, it reminds me of the Northern Lights in Canada but in the daylight.
I once saw three rainbows in one sitting and will probably never see anything again like that in my lifetime.
I’m not sure what a ‘ping list’ is however if it includes photos such as the ‘fogbow’ then yes, please add me, thank you.
Years ago I saw a round rainbow around the sun after a big storm—is that also called a ‘glory’, or something else? One of the most beautiful and weirdest things I’ve ever seen! :-)
Cool, but not exactly what I saw—it was literally a *rainbow* completely circling/ringing around the sun—didn’t last long, but it was so neat to see! Those were the days before cell phone cameras, or else I’d have a pic to remember it by! :-)
I used to have a great picture of my shadow with a glory when I was at the top of Mt. Lassen. Early in the morning with only the very top of the peak above the clouds. I lost it sometime when I moving around though.
The word "ping" on the top of your FR pages will light up to inform you that you have an article or comment for you to read. Click on it and it'll lead you to what you want to read.
If you need further help, freepmail me at "MinuteGal" and I'll be happy to lend a hand.

Thank you very much Leni, i appreciate it. You have been very helpful. ~Dixie
A complete raindow around the sun is called a 'Rand's Rainbow. The pictures below are of a 'Circumhorizontal Arc'. These don't ring the sun but look more like a very wide upside-down rainbow. The pics don't do it justice - it was very vivid! These were taken 06-03-06, Spokane WA, looking south.
This will be a killer for slow connections (I did shrink these quite a bit) but here goes...
If you're on one of these ping lists, you might see a relevant article and send a reply to the person who runs the list, so that he or she can alert everyone on the list and they'll be sure to see the thread. You just type the person's screen name in the "To:" field and tell him about the article.
This link is a list of ping lists on the board.
NASA puts a new picture on the Goddard Space Flight Center site every day. I try to post all of them, but some days I haven't got time, and sometimes I look at the picture and say, "So what?" :)
I see it, too. I also see a faint green on the inside, and I keep telling myself it’s not there . . . :)
Wow, absolutely beautiful! :-)
Looks like daytime aurora borealuses! (sp?)
“Rand’s Rainbow”—thanks! Love to see these IRL too, wow.
We see that display, or part of it, very often here in Fairbanks. Usually the left or right pillar when the sun is low. The overhead patch connects to a horseshoe shape that cross the entire sky and narrows to a white patch opposite the sun.
