Wow, I have only seen this twice in my life and it was awsome both times. The first time I saw one was in Colorado probably sometime in the 90’s.
Today I was doing laundry and went to hang a basket full on the outside line to dry. When I looked up at the line, an awesome sight caught my eye. It was a complete circle rainbow.
I immediately called my husband to grab a pair of sunglasses and to come and look. I was not aware that it was a common occurance, but Mike said, oh, I have seen them many times. Well, perhaps I have lived a very sheltered life because I have only seen two in my 60 years.
The sun was right in the middle otherwise, I would have tried to take a photograph, but it was impossible, so I can only remember what I saw with my own eyes. It was spectaculiar, or at least to me it was.
I was able to find a picture on the Internet so you could see what it looked like, just in case you have never seen one.
