Sundog. I’ve heard they’re a pretty good indicator that it will rain in the area within 24hrs when one is seen. That’s if you believe those wife’s tales.
it is similar to a sundog. the sun in certain conditions will refract at an angle through ice crystals or thin cloud covers and have the appearance of a rainbow, but it is really not a rainbow.
when the sun in setting in the right conditions and is low to the horizon, you can have the same looking sundogs vertically one on each side. Jack
or the picture actually…No, this isn’t an upside-down rainbow, and the photographer hasn’t faked the picture. It’s an unusual phenomenon caused by sunlight shining through a thin, invisible screen of tiny ice crystals high in the sky and has nothing at all to do with the rain.
That was my first thought too Jack, even in the mid of summer its atleast zero at 15 to 20,000′. Flew in a small Cessna one time when I lived in Lacrosse, got up around 1,800′ and it was 65 degrees and 90 degrees on the ground.
I took some pictures of that same formation a few years ago while fishing the Rainbow Flowage. We were able to watch it for all most a half hour. It was pretty neat.
