Something Wonder Full
There is a lot of disinformation about these "Fire Rainbows" on the net. They started showing up about 10 years ago and are NOT rare. I have seen three so far this year.
They can appear at many sun angles and are NOT just seen around a solstice. Note also that the moon now has a COLOR rainbow effect around it at times too. Also that the sun has at times a full circle around it in color too. They are NOT in any of the old textbooks about the atmosphere over ten years ago either.
