Story of the day On 2 May 2021, I saw an impossibly small rainbow. It was made of a minuscule wisp of a cirrus cloud, and unlike when most rainbows form, there was no trace of rain. This was the most unusual rainbow I've seen in my life, It's not possible to post photos on this page, unfortunately, but here's a link to it: robertalfredson.smugmug.com/Misc/i-g5GPhBK/A
