Astronomy for Astrologers

The Celestial/Equatorial Sphere

This diagram represents the Earth and/or the celestial
sphere. The zodiac or ecliptic is surrounding the Earth,
and the North Pole is tilted toward the solstice point.
Then:

1. A late afternoon birth puts the birthplace to the right
   of the Earth/Sun line and toward the twilight region of
   the globe.


2. The birth geographic latitude is 40°.


3. A line from the North Geographic Pole (or celestial
   pole) through the birthplace and on to the South Pole
   represents the RAMC (Right Ascension of the
   Midheaven) for this birth.


4. The point where it cuts or intersects the zodiac is the
   M.C. (25° Virgo).
