Ring around the Moon

Wednesday's blood blue supermoon didn't really perform for us. We are in the wrong place to see the eclipse which would have turned it red. When we left home to walk down to the pub quiz, it was bright and clear, but it didn't look quite full - nearly the perfect circle, but not quite.

By the time we returned, the sky had clouded over. This might have spoiled the effect, but didn't: there was a halo around the moon, and to the naked eye, the concentric rings were of three distinct shades: the disc was outlined in blue, then a broader band of grey, and then a ring of rust red.
