Sidereal folks et al; Let me introduce to Astrologers a method I've played with over the years. I call it a Grand Lunar probably based on error or confusion. It is simply doing a Lunar Return for the time when the transiting North Lunar Node is the same as birth, and these charts occur approximately every 18 years per the Saros Cycle. Many Moons ago, long time it seems, 1970's I remember discussing techniques with a rogue astrologer, Paul Schure, and the subject of Grand Lunar stuck in my head. Now, Bert Fannin always referred to it as when the Moon makes full cycle 27.4 days in the Secondary Progressed Chart. But I remember conversations of some illusive Grand Lunar in a different context.
Has anyone ever done these charts besides myself? I would like to compare notes with other Astrologers. Of course, the concept of an 18 year chart exceeds the time frames we astrologers are not used to working with in Solunars. The big question since the Universe seems to operate on its own clock, we are tasked to use the Lunar Return just prior, or after exact conjunction of the North Lunar Node Return, as the katarche for the Lunar Return, i.e., what I call the Grand Lunar, and which seems to work better.
Locality wise, the charts seem to strongly indicate activities over key areas in the continental United States where I've spent most of my adult life. Such, my rational has been to take the closest actual distance of the North Nodes zodiacal position with respect to its exact Natal position at birth... as the Grand Lunar Return katarche.
My suspicions that this chart may have been utilized by the Celts, or Druids was again ignited watching a recent documentary on Stonehenge. The TV show discussed the Sun and Moon phenomena of Saros Cycles that could be observed at regular intervals through a rectangular space of the Stonehenge blocks structure. The Sun and the Moon could be observed making conjunction in the space, or timely appearences. Hope others out there give it a check, and share their own observations, or results. Lux, Sidereal Bob
