Astrological tables of ephemeris: description and reviews

What are astrological tables of ephemeris? What are they for? In astronomy, an ephemeris is a table of the celestial location of the moon, the sun, planets and other cosmic objects, computed over the same time intervals. For example, at twelve o'clock in the morning every night.

Star ephemerides are called tables, which indicate the apparent position of stars, subject to the influence of nutation, procession and aberration. Also called the ephemeris formula, with the help of which the moment of arrival of the moment of the next moment of the minimum for the darkened variable systems of stars is calculated.

Application

How are ephemeris tables used? With their help determine the coordinates of the observer. This term is also referred to as the position of synthetic earth satellites used for navigation, for example, in the system NAVSTAR (GPS), Galileo, Glonass.

Information about the location of the satellites is presented as part of special messages. Under the circumstances, they talk about the transfer of ephemeris.

Historical editions

It is known that in 1474 Regiomontanus published his famous ephemeris tables in Nuremberg. In this work there were ephemerides for 1475-1506, which were calculated for each day. This book contained tables of positions of the planets, the coordinates of the stars, the conditions for connecting the stars and eclipses.

Modern editions

Today, ephemeris tables are published in the most important astrological collections: The Astronomical Yearbook (published by the RAS since 1921), Nautical Almanac, American Ephemeris, Berliner Astronomisches, Connaissance des Temps. In addition, there are sites with which you can calculate the ephemeris. They are created both by enthusiasts and by professionals.

So, it is known that on the NASA website Espenyak Fred published the data of the positions of the planets of the solar system, the Moon and the Sun for 1995-2006. And on the website of the "Institute for the Calculation of Ephemeris and Celestial Mechanics" there is a calculator of coordinates of space objects. In addition, there is a library with which you can use the Excel sheet to make astronomical calculations using the ephemerides of Switzerland, JPL and Moshier.

Calculation

Tables of ephemerides are in service with each astrologer. Today, the movement of objects around the sun has been studied very well. Various astrological associations have created mathematical forms for the calculation of ephemerides, competing with each other in accuracy. These samples are described in special astronomical publications.

The old theory

The ILE version is an improved theory of Brown. It was first proposed by E.W. Brown in 1919 in his work "Tables of the displacement of the Moon", which was perfected by WJ Eckert in 1954 in the work "Improved lunar ephemeris". Later on, the theory was changed several times.

This model was previously used by F. Espenyak to calculate eclipses provided by the NASA website.

New solution

The version of VSOP82 describes the movement of planets around the Sun. It was proposed in 1982 by P. Brittanyon and published in the astrological almanac "Astrophysics and Astronomy", entitled "The theory of displacement of all planets - VSOP82 solution".

Another version

Version ELP 2000 describes only the ephemeris of the moon. It is printed in the astrological collection Astrophysics and Astronomy in 1983 by M. Shapron-Tuzé and J. Chapron, and also in the article "Ephemerides of the Moon ELP 2000". This theory contains 7,684 periodic terms for the ecliptic latitude of the Moon, 20,560 for the ecliptic longitude, and 9,618 for the distance. The amplitude of the minor members corresponds to 2 cm for the distances and 0.00001 seconds of the arc. In a simplified form, the model is applied by F. Espenyak to calculate the eclipses published on the NASA website.

Publications of the USSR

And what about the national astrology? Based on the DE200 / LE200 version, he published the ephemerides of the Moon, the Sun and the planets "Astrological Yearbook of the USSR" (since 1986).

Model of the JPL laboratory

Version DE403 / LE403 describes the movement of planets around the Sun and focuses on the coordinates of the moon. It was developed by the staff of the JPL laboratory Standish, Williams, Newhall and Faulkner. It is published in the article "Lunar and planetary ephemerides JPL DE403 / LE403" (1995) in a special edition of this laboratory. Today, there are new ephemeris tables developed by the JPL.

Convenient tables

The position of the planets is calculated by astrologers for many years ahead, and the results of the calculations are translated into tables. They contain the data of the visible positions of the planets, which are calculated using a computer, guided by the laws of the mechanics of the cosmos. The positions of celestial objects in the tables are indicated with a specific step indicating the length of time between the two associated moments to which the calculation is performed. It is convenient to apply the following tables in steps of one day:

• The American ephemeris table of Michelson for the 21st century from 2001 to 2050 and for the twentieth century from 1900 to 2000.
• Rosicrucian Ephemerides (1900-2000).
• Raphael's tables (the positions of the planets for each year).

It is known that in the ephemerides of Michelson the position of celestial objects is given on the Greenwich midnight of every day, and the data are presented monthly. On each page, the longitudes of the planets are placed for two months in the form of a pair of blocks (Longitude).

Reviews

Many astrologers like the 1973 ephemeris table. They claim that it is very convenient. Some praise the tables at midnight (2001-2050) and argue that they are an indispensable tool for the work of astrologers and beginners. Experts say that the ephemerides in the book are presented in the form of sections for each month and year. They like that this publication indicates the position and the lights, and the planets in the signs of the Zodiac for any month. Many complain that they had to buy very small tables that people with poor eyesight find it difficult to read. Some people do not like the quality of printing and binding of certain publications.

Horoscope

Why do we need ephemeris tables? By the date of birth with the help of them you can compose your own horoscope. What it is? Our horoscope is the ratio of the planets describing the circles around the Sun in time and space that was formed by the time of our birth in a certain place on Earth.

The base of each horoscope consists of an ecliptic - a large circle, along which the annual visible movement of the Sun, or rather, its center, takes place. It is considered as a cross-section of the celestial sphere by the plane of the earth's orbit, since the movement of the Sun reflects the rotation of the Earth around it.

The movement of the planets is established in the plane of the ecliptic. Their position, viewed from the point of view of the terrestrial observer, can always be accurately calculated by ephemeris. At the same time, there may be some connections between planets, which are called aspects. They are also noted in the horoscope.

In order to compose your own horoscope, you need to know the exact time of your birth. Without this nuance, drawing up a scheme is impossible. In order to learn how to compile a natal chart on your own , you need to have at your disposal the ephemeris tables, the world atlas, the "House Table" and the calculator.
