The marked body is tonight's Moon. Its path is tilted 5.15° to the ecliptic, which is tilted 23.44° to the celestial equator. When the two tilts point the same way, the Moon can reach 28.6° from the equator; opposed, only 18.3°.
The tilts do not stay put. The Moon's path turns, its two crossings of the ecliptic, the nodes, sliding west once round in 18.6 years. So the Moon's greatest reach north and south swings slowly between the two extremes and back.
Forty years of the Moon's farthest north, month by month. The peaks are the major standstills, the troughs the minor ones. At a major standstill the Moon climbs five degrees higher than the summer Sun ever does, and sets far further north.
The word is old: at a standstill the Moon's rising point along the horizon stops widening and turns back, month after month, for a year or so. Anyone watching moonrise against a mountain skyline across two decades would see it, and some monuments line up with it.
