The term "lunar standstill" is used to describe the extremes in lunar declination. The moon doesn't really stand still, but it does stand still in declination while it reverses direction (think calculus and sine waves). The most extreme ranges in declination due to the moon's orbital tilt occurred in 2006. In another 8 years, the range in declination will be at its lowest.
