Western Solar Sector

Solar Sector refers to the part of an Eastern or Western horizon where the moon's Lunistices Lunistices are the most northerly and southerly moons of the month. The lunar equivalent of solstices. More. never occur. The central part of the tropical year, sur­rounding the Equinox and spreading to just beyond the Cross-Quarters. This part of any luni-solar horizon calendar requires the least precision. Within that sector and at these latitudes, the sun moves by about its own diameter daily but the motion of the moon appears to be unmeasurably erratic. In the Western Solar Sector it is possible to observe and measure Sun Sets:

• From Imbolc / Brigit's day (WXQ) through Spring Equinox, to Bealtaine / May Day (SXQ).
• From Lughnasadh / Lammas (SXQ) through Autumn Equinox, to Samhain / Martinmas (WXQ).

Notice common themes and variations. Remember that, for any site, this horizon sector may well not be the most important one.

• Vertical scale is x4 to make it easier to see the patterns.
• 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].
