Upside Down Rainbow

"Can you see it?  There it is!"  As my class oohed and ashed at the upside down rainbow I couldn't for the life of me see it.  All I could see was the sun, I was getting quite frustrated then I notice that everyone was looking above my head.  Then I saw it, an upside down rainbow, apparantly it's to down with light passing through ice crystals and is quite a commonish sight up north.  It even featured on the evening news (not my photo as people assumed but one from a parent who had also seen it).  My favourite moment was the whole class running to see it and one little girl took out the IPad, to capture a moment I thought.  "Oh, did you take a photo?"  "No, I'm doing a quiz!"
