在这张11月18日的快照中，满月离地球的阴影不远。在西西里岛上空，最明亮的月相被过往的云遮住了。在高高的薄云的边缘，有一些大小差不多的小水滴，把整个月光弄得暗淡无光。由此产生的虹彩像月球日冕一样闪耀。那天晚上，满月也出现在昴宿星团附近，出现在彩虹云岸的左下方。七姐妹的星星很快就会和一个更暗、更红的月球圆盘分享天空。

In this snapshot from November 18, the Full Moon was not far from Earth's shadow. In skies over Sicily the brightest lunar phase was eclipsed by passing clouds though. The full moonlight was dimmed and momentarily diffracted by small but similar sized water droplets near the edges of the high thin clouds. The resulting iridescence shines with colors like a lunar corona. On that night, the Full Moon was also seen close to the Pleiades star cluster appearing at the lower left of the iridescent cloud bank. The stars of the Seven Sisters were soon to share the sky with a darker, reddened lunar disk.
