The New American Ephemeris for the 21st Century 2000-2100 at Midnight, Michelsen Memorial Edition Compiled and Programmed by Rique Pottenger, based on the earlier work of Neil F Michelsen Memorial text and Introduction compiled and written by Maria Kay Simms In 1976, Neil F Michelsen (1931-1990) compiled, programmed and published the first edition of The American Ephemeris that set new standards of accuracy for contemporary astrology. In 2006, celebrating the 30th anniversary of first publication of the first volume of work that grew to become Michelsen's comprehensive American Ephemeris series, Rique Pottenger continued the work that Neil began. Within The New American Ephemeris for the 21st Century 2000-2100 at Midnight is the familiar data and format long used and trusted by astrologers worldwide, now updated and expanded, with new features. This ephemeris is unique among others in the series for its memorial text section that documents, partially from excerpts from Michelsen's own writing, and partially from testimonials of colleagues, a history of the development of computer technology for astrology. Features of this entire 21st century edition include improvements in the computer generating program that enable finding double ingresses in a single day plus more accurate station times. Ceres, the asteroid that was elevated to planetary status by the IAU (International Astronomical Union) in 2006, has been added to the daily longitude listings in her position between Mars and Jupiter. The new planet Eris, whose discovery precipitated the IAU decisions of 2006, moves, at most, about 3 minutes per month, so her position is listed once per month in the Astro Data box, along with monthly positions for Chiron, Pallas, Juno and Vesta. A new formula increases the accuracy of monthly positions of the Galactic Center. Phenomena listed in the Astro Data column are sorted by time as well as by date. Also, the planetary ingress data includes R if the planet is retrograde when it ingresses.

The American Ephemeris 1950-2050 at Noon, 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 future transits for most people he or she might encounter. 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, which is published in two versions. This one is calculated for noon UT, and the other for Midnight UT. 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. 978-1-934976-27-2 624 pages $29.95

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.
