(astronomy) the angular distance of a celestial point measured westward along the celestial equator from the zenith crossing; the right ascension for an observer at a particular location and time of day.
right ascension error of about 0.6 second is introduced.
Using the Snell's law in polar coordinates, the ionospheric refraction effects on the declination and right ascension determination is discussed in this paper.
Each search area is about 10 degrees in declination and one hour of right ascension.
Latin: “Balance”), in astronomy, zodiacal constellation lying between Scorpius and Virgo, at about 15 hours 30 minutes right ascension (the coordinate on the celestial sphere analogous to longitude on the Earth) and 15° south declination (angular distance south of the celestial equator).
(astronomy) the angular distance to a point on a celestial object measured north or south from the celestial equator; expressed in degrees; used with right ascension to specify positions on the celestial sphere.
opposition in right ascension
A large reflect meridian circle is an instrument for the absolute determination of the declination and right ascension of a star.
From our perspective they appear in the constellation of Taurus, with approximate celestial coordinates of3 hours45 minutes right ascension and+24 degrees declination.
