I was enjoying my morning coffee on a cold clear day.

I glanced out the window where the sun's early rays were giving a lustre to the snow covered lawn. Then I noticed a brilliant 'sun dog'. I have seen a lot of sun dogs in the past but I can't remember one that was bigger or brighter. For those who do not know what a sun dog is it is a rainbow caused by the sun shining through ice crystals in the air.
