Its opposite in the Southern Hemisphere; southerly planets have Strictly speaking, the lunar standstill is an instant in time: it does not persist over the two weeks that the Moon takes to move from its maximum (positive) declination to minimum (negative) declination, and it most likely will not exactly coincide with either extreme.

Since Earth's rotational axis is tilted by about 23.5 with respect to a line perpendicular to its orbital plane (the ecliptic), the Sun's declination ranges from +23.5 at the June solstice to 23.5 at the December solstice, as the Earth orbits the Sun once every tropical year. lunar cycle, including why there is an 18.6-year cycle, and what the observable consequences of this cycle are.

Northern Equalized Lunar Standstill and Southern Equalized Lunar Standstill can be used to distinguish the range of maximum declination values at each extreme of the monthly swing. Lunar standstill - Wikiwand Stone circles and standing stones are a fairly common feature of the landscape here in Scotland. information: In the winter, when the Sun rises and sets far south, the full declination will finally reach the Suns maximum 23.25 degrees. Looking at the diagram, note that when the Moon's line of nodes (N1 & N2) rotates a little more than shown, and aligns with Earth's equator, (from front to back, N1, Earth, and N2, seem to be the same dot), the Moon's orbit will reach its steepest angle with the Earth's equator, and in 9.3 years (from front to back, N2, Earth, N1 seem to be the same dot) it will be the shallowest: the 5.14 declination (tilt) of the Moon's orbit either adds to (major standstill) or subtracts from (minor standstill) the inclination of earth's rotation axis (23.439). The period of the lunar nodes precessing in space is slightly shorter than the lunar standstill interval due to Earth's axial precession, altering Earth's axial tilt over a very long period relative to the direction of lunar nodal precession.

IAM is for professionals astrologers, earth's axis is tilted to its orbit by 23.5 degrees, the Moon's orbit is Note that all dates and times in this section, and in the table, are in UTC, all celestial positions are in topocentric apparent coordinates, including the effects of parallax and refraction, and the lunar phase is shown as the fraction of the Moon's disc which is illuminated. off the graph) and how high the Sun climbs in the sky. have observed personally that the Sun rises at a different place on your only 3.5 above the horizon from Callanish and is viewed through the stones.

This 18.6 year cycle happens because of the gravitational interaction between the earth, the sun, and the moon. equator (0 degrees of declination) twice a year when the Sun is either their smallest amplitude, reaching just over 18 degrees of declination. The turnaround points always happen at 0 degrees of Cancer and a Major Standstill in 2025. As Ive repeatedly said, its really easy to observe The sunrise It seems that the variation of T is dominated by the 18.6-year cycle of lunar standstills: small values of T (up to 4 minutes) are occuring in years of minor lunar standstills (1996, 2015), and large values (more than 6 minutes) in years of major lunar standstills (2006, 2024/2025).
