A rainbow is caused by the Sun shining on moisture droplets, most commonly in a post-rain atmosphere. A moon bow is much rarer, only seen at night when the moon is low and full to almost full. One popular place to see moon bows is at Cumberland Falls in Kentucky, as pictured above.
I saw a large moonbow chunk late at night in the 70s once. The full moon was positioned in the central grip of a long cloud formation that looked like a pair of tongs.
I like number 4 and 13. I remember the tornado in Edmonton 20 years ago and the sky was black, almost like night in the middle of the day. I should have taken pictures of it. I think I still have the newspaper cover page with a pic kicking around somewheres...
