This post has been the most viewed and the most commented on this blog since I wrote it a couple of years ago. When you see one of these, it blows you away, and I nearly drove off the road staring at it. I love that so many people get to see a rainbow around the sun, and are as amazed and as compelled as I was to look for information. I wish I could “bump up” the post but I can’t so here’s the link to it. Be sure to read the comments to see all the other readers’ sightings!
