No astrologer's library can be complete without the ephemeris with the latest data from NASA's Jet Propulsion Laboratory. The Anerican Ephemeris by ACS is the most accurate ephemreis in the world today. In addition to planetary positions for every day from 2000 through 2050, it includes a wealth of data - solar and lunar eclipses, aspectarian of Jupiter though Pluto, Chiron, Synetic Vernal Point, Moon phases and more.

An excellent ephemeris., August 29, 2002

Reviewer: David R. Schryer (see more about me) from Hampton, VA United States

As a serious astrologer I have hundreds of dollars worth of astrological software. but I also have the midnight version of this excellent ephemeris. No astrologer should be without an accurate ephemeris, and those compiled by Neil Michelsen are the best -- highly accurate and very user friendly. If you prefer a noon ephemeris, this is the one to get.

The only ephemeris you need for the next 50 years., June 9, 2001

The serious astrologer's ultimate tool for drawing up birth charts, calculating progressions, and following the transits, eclipses, and moon phases that affect us all. A must have!

The American Ephemeris for the 21st Century at Noon, May 2, 2000

This must have ephemeris has several wonderful features which make it extraordinarily helpful to the beginner or advanced astrologer. I especially appreciate the gray highlighting used when each of the planets is retrograde. In addition, the exact timing of lunations, eclipses, Moon and planetary ingresses into the various signs, and timing of major aspects for each month are very helpful. This book opens with a Phenomena Section Explanation which is concise and understandable for even the first-time users of an ephemeris. Last but certainly not least, the typeface used is remarkably readable which is so important with such a numerically based work. Hats off to Michelsen and Pottenger -- their 20th Century Ephemeris was brilliant and they've moved on to the 21st Century with the same helpful style.
