Barium Rainbow
January 4, 2008 by engtovo
I forgot to post this the other day, I was driving to town when I noticed this rainbow straight up and down. There was no rain, snow or other moisture in the area at all. There were a few clouds some chem haze and low humidity.
Here I enhanced some settings so it could be seen better and you then can see the sun hitting the barium over a large area to the left of this “rainbow” area
when i first looked at your photos i though i saw the aurora borealis, but a second look i can see a rainbow
