Right Ascension
Science / Astrology / Right Ascension
Right Ascension: Measurement along the celestial equator eastward from 0° Aries that describes planetary positions in terms of degrees, minutes and seconds, not zodiacal signs.
Right ascension can therefore be measured in degrees or hours. Whereas terrestrial longitude uses meridians of longitude, right ascension uses hour circles which run between the north and south celestial poles.
Right Ascension: This is a measurement moving eastward along the celestial equator.
Right Ascension. Distance measured along the celestial equator, Eastward from the point of the Spring Equinox; or, as sometimes described, distance along the circle of declination. v. Celestial Sphere.
Right Ascension. See "Ascension, Right."
Rising Sign. The sign that is on the Ascendant.
Right Ascension: See 'Ascension.'
Ruler:
The Ruler of a horoscope is that planet which has greatest dominion and influence over the life, and to which the native most readily responds.
right ascension Measurement along the celestial equator eastward from 0° Aries that describes planetary positions in terms of degrees, minutes and seconds, not zodiacal signs. Sidereal time expressed in unit of arc.
Right Ascension: the arc on the celestial equator extending eastward from the vernal equinox to the meridian of the object in question in the equatorial coordinate system. This coordinate corresponds to longitude on the Earth.

Sidereal TimeRight ascension of the meridien at mean noon (or midnight in modern ephemerides). The angular distance of the first point of Aries, or the true vernal equinox quoted in hours, minutes and seconds.
Distance north or south of the celestial equator is measured in what's called declination (degrees, minutes and seconds), while distance along the equator is measured in what's called right ascension (degrees, minutes and seconds, ...
Among the meanings are right ascension, hour angles, equal hours, longitudes and azimuths. It would not be possible to label all of these uses in a coherent way.
The first step is to recognize that no planet is ever less than zero degrees (0°) or exceeds 29° 59' by longitude regardless of the sign they are located (unless you use the Right Ascension).
A rather more complicated version of the Placidus system, built on equal increments of Right Ascension for each quadrant. The Koch system is defined only for latitudes between 66°N and 66°S. This system is popular among research astrologers in the U.
Diurnal arc - The time expressed in right ascension that it takes a planet or degree of the zodiac to move from its rising point on the horizon to its setting point.
Diurnal planets - Saturn, Jupiter, Sun.
Equatorial Arcs: A method of progressing house cusps, based upon the Earth's rotation, in which one year of life corresponds to the passage of 1° right ascension over the meridian, approximately four minutes of time.
It is time determined in relation with the passage of Sun across the meridian: at mean noon, 12 o'clock local mean time (LMT) on any day, sidereal time is the Right Ascension (q.v.) of the fictitious mean Sun which is defined as the tropical mean ...
the equatorial coordinate system, the angle that an object is above or below the Earth's equator projected on the celestial sphere. This coordinate corresponds to latitude on the Earth. The other coordinate in this system is called "Right Ascension." ...
What is arbitrary is that this point is taken astronomically as 0 in terms of Right Ascension.
right ascension: the angle measured in units of time 15° = 1h eastward along the celestial equator from the vernal equinox to the foot of the hour circle through the object. Symbol: or α or R.A.
