Today I had a spectacular view of a 180 degree rainbow over Maeshowe, #Orkney and also something I've never seen before: A reflection #rainbow, where light has bounced off water (over the hill) before refracting in the atmosphere. Spent some time going "huh?" before finding a website that explained it.
I was also inside the tomb close enough to midwinter to see the sun shine along the entrance passage into the core - but while special, that was less exciting than the unusual rainbows!
