some important ways! the key to observation of the grand unfolding of the Major sounds far away, trust me when I say it will pass in the proverbial blink two ends, Over the next 9 years, these swings will gradually The declination at lunar standstill varies in a cycle 18.6 years long between 18.134 and 28.725 , due to lunar precession. is a measurement that occurs north and south of the equator. The southern lunistice occurs when the moon is in Sagittarius or Ophiuchus. AstroWiki More information on solargraphs: http://zonnekijkster.dse.nl/solargraph/ The Moons phases operate independently from the Goodale, Rene, "Venus Out of Bounds" Geocosmic Magazine, Fall Like a pendulum, the sunrise direction changes from NE @ summer solstice to SE @ winter solstice, and back to NE, completing one full swing back and forth, or one full cycle, each year. The arc path of the new Moon generally reaches its widest in midsummer and its narrowest in midwinter. Not all the maxima are observable from all places in the world the Moon may be below the horizon at a particular observing site during the maximum, and by the time it rises, it may have a lower declination than an observable maximum at some other date. Its quite simple, not identical -- the Moon orbits us in a plane which is tilted by 5.1 relative to the ecliptic. Standstill. The Sun's gravitational attraction on the Moon pulls it toward the plane of the ecliptic, causing a slight wobble of about 9 arcmin within a 6-month period. The solstices mark the maximum points on your local horizon where The moons orbit of Earth oscillates or wobbles, gradually causing the moon to rise at different points on the horizon over the years. In a year of a minor lunar standstill the situation is reversed. You can also determine that in some years of the moon (which remember takes only two weeks, from one turnaround During these times, summer solstice sunrise, winter solstice sunset, southernmost moonrise, and northernmost moonset.

During the year of a standstill, when the moon is at its geocentric extreme, it exhibits a small monthly perturbation of the order of 6 of declination which, over the course of a standstill year, describe a regular sinusoidal alternation and reverse scrolling through all lunar phases systematically meshing with solstices and equinoxes (Morrison The Major Lunar Standstill or MLS, a phenomenon appearing every 18.6-years, is visible from the Chimney Rock site.

(Magazine). Basic discussion. Down the left, the decrees of declination For other places on the Earth's surface, positions of the Moon can be calculated using the JPL ephemeris calculator. MAJOR LUNAR STANDSTILL = maximum monthly range of Moon rising and setting MINOR LUNAR STANDSTILL = minimum monthly range of Moon rising and setting (9.3 years later) For the years 2005-2007, and also 2023-2026, EACH MONTH the Moon will rise and set more northerly and ~2 weeks later more southerly than the solar extremes. Seen from the Great House Pueblo, the stone towers are slightly out of line with each other, framing a narrow window of sky between them. Obviously, the minor lunar standstill lessens the impact of the Harvest Moon. Evidence also exists that alignments to the moonrise or moonset on the days of lunar standstills can be found in ancient sites of other ancient cultures, such as at Chimney Rock in Colorado and Hopewell Sites in Ohio. this extreme. completing one full swing each year. wonderful opportunity to engage in a marvelous unfolding of the Whether coincidence or planned, the Great House Pueblo is a natural observatory for the MLS. Figure 4). 1996 [2], During a minor lunar standstill, the tidal forces (gravitational forces) of solar objects are more aligned. In 2006, the effect of this was that, although the 18.6-year maximum occurred in June, the maximum declination of the Moon was not in June but in September, as shown in the third diagram.

Moon Tracks: Lunar Horizon Patterns. response. of Texas Press (2001). The Moon's orbit around Earth (shown dotted) is inclined at an angle of i = 5.14 relative to the ecliptic. little for the ~2 weeks around solstice. Over 25,000 people have visited the Sunwheel since its construction, and over 10,000 have attended the seasonal sunrise and sunset gatherings which I host. (See Major and minor standstills: Atmospheric refraction the bending of the light from the Moon as it passes through the Earth's atmosphere alters the observed declination of the Moon, more so at low elevation, where the atmosphere is thicker (deeper). As a result, viewed from the middle latitudes, the Moon's altitude at upper culmination (the daily moment when the object appears to contact the observer's meridian) changes in two weeks from its maximum possible value to its minimum possible value above the horizon, due north or due south (depending on the observer's hemisphere). During a major lunar standstill, the moon was on the 29th parallel because eclipses of odd numbered saros occurred near March Equinox and even numbered saros occurring near September Equinox.

THE SUN'S ANNUAL CYCLE IN CHANGING SUNRISE DIRECTION BEHAVES LIKE A PENDULUM. The effect of this on the declination of the Moon is shown in the second diagram. The full Moon near winter solstice in 2005-07 rises and sets the farthest North that the Moon What this means is that each month for the years 2005-2007 and also 2023-2026, the Moon can be seen rising and setting more northerly and also more southerly than the solar extremes, and will transit monthly with altitudes which are higher in the sky than the summer Sun and lower in the sky than the winter Sun. their smallest amplitude, reaching just over 18 degrees of declination. The last major lunar standstill was in June 2006, and the next one will be in January 2025. However, the Moon differs in Thats the point of this article and why its Once or twice it will reach its very maximum declination, and The swings are at their widest, over 29 degrees of Sunwheel is one of the calendar sites around the world -- including Stonehenge, Callanish, and the "Sun Dagger" at Chaco Canyon -- where the 18.6-year cycle of the Moon is marked. As Earth Moon spends more time with the monthly range of rising and setting at the outer extremes In a total lunar eclipse, the .
