Rique Pottenger Books

A new full 21st century ephemeris, fully updated from prior versions of The American Ephemeris series with the most recent available data, including the addition of Ceres to the daily planet lineup and Eris, plus the asteroids Pallas, Juno and Vesta to the monthly positions, that also include Chiron and an improved calculation for Galactic Center, plus other refinements of data such as the ability to find double ingresses on a single day and more accurate station times. This book is dedicated to its orignator Neil F. Micheslen, and includes his chart, memorial text from his writings and commentary from others capsulizing the early development of computer technology for astrology.

Since the 1976 publication of his first version of The American Ephemeris, 1931-1980, Neil F. Michelsen's ground-breaking series of ephemerides have consistently set standards for accuracy in astrology, becoming indispensable to astrologers worldwide at every level from student to professional. The tradition continues with this Revised & Expanded Third Edition of The American Ephemeris for the 21st Century, 2000-2050 at Midnight. Revisions and additions are programmed by Rique Pottenger, who became head programmer for ACS Publications after Michelsen's passing. Additions and improvements include new Jet Propulsion Laboratory data and programming refinements that enable finding double ingresses in a single day plus more accurate station times. A new formula increases the accuracy of the Galactic Center. Phenomena in the Astro Data section are now sorted by time as well as by date, and R appears with Planetary Ingress Data if a planet is retrograde when it ingresses. The most notably obvious additions include the dwarf planet Ceres in daily longitude listings between Mars and Jupiter, and monthly positions are given for Eris, Chiron, Pallas, Juno and Vesta.

Whether you are planning to attend astrology classes or complete your certification, the American Ephemeris is an absolute necessity for hand-calculating charts or tracking transits. With Astro's high standards of accuracy and the very latest data from NASA's Jet Propulsion Laboratory, this reference book is the most accurate ephemeris in the world and an indispensable part of every astrologer's library. In addition to planetary positions for every day, it includes a wealth of data including solar and lunar eclipses, an aspectarian of Jupiter through Pluto, Chiron positions, Synetic Vernal Point, Moon phases and more!
