   Explanation: On March 14 the Moon was Full. In an appropriate
   celebration of Pi day, that put the Moon 3.14 radians (180 degrees) in
   ecliptic longitude from the Sun in planet Earth's sky. As a bonus for
   fans of Pi and the night sky, on that date the Moon also passed
   directly through Earth's umbral shadow in a total lunar eclipse. In
   clear skies, the colors of an eclipsed Moon can be vivid. Reflecting
   the deeply reddened sunlight scattered into Earth's shadow, the
   darkened lunar disk was recorded in this time series composite image
   from Cerro Tololo Observatory, Chile. The lunar triptych captures the
   start, middle, and end of the total eclipse phase that lasted about an
   hour. A faint bluish tint seen just along the brighter lunar limb at
   the shadow's edge is due to sunlight filtered through Earth's
   stratospheric ozone layer.
