THE AMERICAN EPHEMERIS FOR THE 21ST CENTURY AT MIDNIGHT 2000-2050, 2E, is the most essential (#1) astrological reference book. Daily planetary positions from 2000-2050, moon phases, eclipses, void of course times, aspects, direct and retrograde station times, and "astrological weather" are included.

Compiled and programmed by Neil F. Michelsen; revisions by Rique Pottenger.

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 Noon. 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 in this new edition 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.

Astrologers worldwide made the late Neil F. Michelsen's American Ephemeris series best sellers. In 2006, Rique Pottenger revised and updated Michelsen's earlier work with The New American Ephemeris for the 21st Century 2000-2100 at Midnight, complete with newly named planets Ceres and Eris, plus much more. Now, following the debut of the big full century book, astrologers will find this new, lightweight 14-year version a "must have!" In easy -to-scan 8.25 x 11 format, it has all the new features of its forerunner and even more. For each month you'll also find a daily Declination and Latitude Table and a detailed Daily Aspectarian. Both Ceres and Chiron are included in daily longitude positions, and in the aspectarian. In Declination and Latitude, Sun through Saturn (including Ceres) are given daily, with Chiron, Uranus, Neptune, Pluto, Pallas, Juno, Vesta and Eris in 5 day increments.

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.
