LunisticeLunistices are the most northerly and southerly moons of the month. The lunar equivalent of solstices. More.
Range is the part of any horizon quadrant within which Lunistices always rise or set. Strictly speaking this lies between the Major & Minor
Standstills
Lunistice positions vary cyclically over an 18.6 year period but are fairly static for more than a year at either end of the range
but always overlaps with a part of the solar zone, from beyond the Cross-Quarter to the Solstice and back.
Thus solar markers may be conveniently used as delimiters for the minor end of the lunar period.
This is the most important part of any horizon quadrant because both lunar and solar measurements require precision as well as accuracy.
Due to the effects of Lunar Horizontal Parallax the relationship between solar and lunar positions differs between Northern and Southern ranges.
With Settings in the North-West, it is possible to observe and measure:
- Monthly North Lunistices:
Starting at Winter Solstice full moon, progressing to waxing quarter near the equinox, ending as a thin waxing crescent some weeks before Summer Solstice.
- The Summer Sun: From Bealtaine / May Day to the Summer Solstice and back again to Lughnasadh / Lammas.
Notice common themes and variations. Remember that, for any site, this horizon sector may
not be the most important one.
- Orange Solar trajectories split the tropical year into 48 "Tweeks" (7.6 day mean) that are better regarded as quarter-months.
- Solid Blue Lunar lines split cyclical lunistice position variation into 16 periods of about 14 months each.
- Lunistices are the most northerly and southerly moons of the month [More].
