   Explanation: 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.
