Former publication for professional astrologers and students concerned with sidereal aspects of astrology. Among astrologers, there are several systems of calculating the divisions of the horoscope chart and devising its relation to the actual stars that constitute the 12 signs of the zodiac. The sidereal zodiac places the division according to the present locations of these signs, which, because of a phenomenon known as the procession of the equinoxes, are constantly changing.
