The highly irregular lunar orbit makes the Moon's appearance change in subtle but significant ways.  Can you find them all?  Hint: keep an eye on Mare Crisium, the "dot" near the right edge of the Moon.  The calendar correctly shows the Moon's daily changing axial position angle, fraction and angle of illumination, apparent size, and librations.  Note: Celestial North is "up" in all views.
