Declination is measured from Earth’s centre. Rise bearings apply to latitude 51.5074° at an ideal 0° horizon. Major standstill brings the widest north-south range of Moonrise over an 18.6-year cycle; minor standstill brings the narrowest. The recent major standstill centred on 2024–2025, with the next minor period around 2034 and major period around 2043.
