Astronomy for Astrologers
- Ann Arbor is located along the 42nd parallel of Earth
latitude. - The North/South geographic meridian (red arc)
passes through Ann Arbor. - This geographic meridian equal is then projected onto
the Equatorial Celestial Sphere. - All points located along this celestial meridian will be
aligned with and in conjunction with the North/South
geographic meridian for Ann Arbor. - However, only the upper star is also conjunct by
declination (= latitude) for Ann Arbor. - The planet Jupiter (shown) would be overhead but to
the South of Ann Arbor, while directly overhead a city in
South America. - However, all of the points/objects shown would be
conjunct the Midheaven for this chart.
At this point, it is hoped that the reader has some notion
of how the geographic sphere fits or matches the
equatorial sphere. Perhaps it is clear to you why the
equatorial coordinates—right ascension (RA) and
declination—are so important in mundane astrology
(politics, etc.). For one, any planetary position can be
matched to a spot on the Earth by both longitude and
latitude, and this is what is done when we trace eclipse
paths on the globe. There is not available space here to
go into great detail on this subject; however, if the
reader understands the simple relationship between the
geographic and mundane (equatorial) spheres, many
interesting ideas may occur.
