. The moon reaches both a northernmost and southernmost position every 29 days, but from month to month the northern and southern limits of moonrise and moonset change. “Over an 18.6 year cycle, the greatest northern and southern positions of the moon extend beyond those of the sun,” the Observatory said. “And just as the sun lingers at its limits at each solstice, once the moon reaches these extremes, its limits don’t seem to change.”

While the sun stands still for just a few days, a major lunar standstill can last for two years. During this time, we observe the moon rising and setting at its most northerly and southerly positions on the horizon, the Observatory said.
