📝 Description: The American Ephemeris 1950-2050 at Midnight

The American Ephemeris 1950-2050 at Midnight, The Trans-Century Edition, is published in response to multiple requests for a one hundred year ephemeris covering these "most useful years." With the years 1950 through 2050, only one ephemeris needs to be at hand, especially when traveling, for an astrologer to do quick lookups of both birth data and transiting data over the expected life span of most people currently living. Since the 1976 publication of the first version of The American Ephemeris, 1931-1980, Neil F. Michelsen's ground-breaking series of ephemerides for astrologers have consistently set standards for accuracy in astrology, becoming indispensible to astrologers worldwide at every level from student to professional. The tradition continues with the addition of this new tropical ephemeris spanning from mid 20th century through mid 21st century. Rique Pottenger has revised and expanded the Michelsen programming with updated Jet Propulsion Laboratory data and improvements in the computer generating program that, for example, enable finding double ingresses in a single day, plus more accurate station times. A new formula increases the accuracy of the Galactic Center calculation. Other new features have been added, the most obvious of which are the dwarf planets Ceres and Eris, in response to the 2006 decisions of the International Astronomical Union. Monthly positions have also been added for the remaining three of the former four major asteroids in wide use among astrologers, Pallas, Juno and Vesta, and also for the centaur, Chiron.

This is a rigorous technical reference, not a narrative guide or introductory text. It serves as the essential reference for charting lives using precise tropical positions derived from JPL data. While it is indispensable for professionals requiring accurate planetary coordinates for transit analysis, it does not suit casual hobbyists seeking interpretive advice or beginner students needing conceptual explanations of astrological symbols. Those looking for a conversational tone or quick horoscope-style readings will find its dense numerical format inaccessible. It is strictly for the serious practitioner who values exactitude over accessibility in their quest for celestial truth.

Almost perfect

This exceeded my expectations. The language takes some getting used to, but it becomes part of the charm. Not a light read, but far more accessible than I feared. Recommended with reservations.

Almost perfect

Perfect companion for my morning study sessions. It pairs well with more modern commentaries on the same tradition. It assumes more background than a beginner might have. Still worth having on the shelf.
