The Uranian Transneptune Ephemeris for 1900-2050 at Midnight is a specialty edition from the standard setting American Ephemeris series. Compiled and programmed by Neil F. Michelsen, it provides 150 years of positions in 5-day intervals for the Uranian Transneptunian points, or hypothetical planets, first identified by Alfred Witte and Fredrich Sieggruen in Germany in the 1920s. Witte first noticed that four points in space appeared to behave in every way the same as planets, although no physical bodies had been actually found there. Later, Sieggruen identified four more points. Some suppose that the TNPs (as they are called for short) could be mathematical points, like nodes, that reflect combinations of energies. No one really knows, but it can be said that after nearly a century of observation of the points in space, Uranian astrologers are convinced of their validity, and have verified consistent patterns in how to interpret their meaning. This volume is provided for ease of use in quickly scanning for the positions of each of the eight TNPs over lengthy periods of past history and also for projecting into the future. The introductory text in the book provides keyword interpretations for the TNPs and a resource guide for where instructional and interpretive books, tools and materials can be found.
