The Full Moon rising on December 22, 2018, the day after the winter solstice, in a perfectly clear sky and over the distant horizon to the northeast over the snow-covered prairie. Some cows are grazing at left! The top edge of the Moon has a green rim and the bottom edge a red rim, from atmospheric refraction. But it made for a Christmas-coloured Moon ornament on the horizon! The dark lunar mare and even the bright rays splashing from Tycho at bottom are visible.
