Deniz ve hava seyrüseferlerinde, "magnetic declination" yerine, "magnetic variation" terimi kullanılır ve açıya pusula sapması veya manyetik sapma denilir. Diğer hallerde, "magnetic declination", manyetik sapmanın, alçalış veya yoğunluğun zamana göre normal veya normal olmayan değişmesini gösteren "magnetic variation" deyimiyle aynı manaya gelmez. Ayrıca bakınız: "magnetic variation", "declination"

Angular distance north or south of the celestial equator to an astronomical object, measured in degrees of arc along the hour circle passing through the object Analogous to geographic latitude on the Earth
(pronounce: dek-lih-nai-shun) declinatio = [Latin] turning aside The declination is the coordinate in the equatorial coordinate system in the sky that is similar to latitude on Earth It ranges between -90 degrees at the southern celestial pole and +90 degrees at the northern celestial pole and is zero at the celestial equator The other equatorial coordinate is the right ascension
the angular distance of a celestial body from the celestial equator along the hour circle to the body It is measured in degrees from 0 to 90, and named north or south of the celestial equator Declination is analogous to latitude on the earth
Declination is the angular distance on the celestial sphere north or south of the celestial equator It is measured along the hour circle passing through the celestial object [1]
(1) In geometry, for a spherical coordinate system, the angle at the centre of a sphere between the equatorial plane and a line to a point on the sphere (2) The arc between the Equator and a point on a great circle perpendicular to the Equator (3) In astronomy, the angular distance of a star or planet above or below the celestial Equator (4) Magnetic declination is the angle between true (geographic) north and magnetic North (the direction of the magnetic compass needle), from the point of observation This angle varies for different locations and continually changes with time due to the wandering of the magnetic north pole (5) Grid declination is the angle between grid north on a grid reference system (e g U T M Grid or Military Grid) and true (geographic) north (In navigation, the term variation is also used)
One of two measurements of the position of an object in the sky Declination measures in degrees from 0 to 90 the position of a celestial object north or south of the celestial equator, just like latitude measures positions on the Earth north or south of the equator The other coordinate is right ascension
along with Right Ascension, this determines a position on the sky Declination is measured north (+) and south (-) from the celestial equator and specified in degrees and minutes
Celestial coordinate that measures the angular distance of a body north or south of the celestial equator along the hour circle passing through the body
The angular distance of any object from the celestial equator, either northward or southward
a polite refusal of an invitation (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
One element of the astronomical coordinate system on the sky that is used by astronomers Declination, which can be thought of as latitude on the earth projected onto the sky, is usually denoted by the lower-case Greek letter delta and is measured north (+) and south (-) of the celestial equator in degrees, minutes, and seconds of arc The celestial equator is defined as being at declination zero (0) degrees; the north and south celestial poles are defined as being at +90 and -90 degrees, respectively When specifying a comet's location on the sky, one must state the right ascension and declination (with equinox), along with date and time (since a comet moves with respect to the background stars) For examples of how right ascension (R A ) and declination (Decl ) appear on a star atlas, see the Millennium Atlas
In astronomy, the angular distance of a celestial body above (north, plus) or below (south, minus) the celestial Equator Magnetic declination is the angular difference between magnetic north and true (geographic) north at the point of observation; it is not constant but varies with time because of the "wandering" of the magnetic north pole
A system for measuring the altitude of a celestial object, expressed as degrees north, or south, of the celestial equator Angles are positive if a point is North of the celestial equator, and negative if South It is used, in conjunction with Right Ascension, to locate celestial objects
The positions of stars and planets on the celestial sphere can be plotted using right ascension or R A and declination These are the equivalent to latitude and longitude on Earth Declination is measured North or South from the celestial equator in degrees, arc-minutes and arc-seconds The celestial poles are at a declination of 90°N and 90°S Stars always have the same R A and dec, because they do not move on the celestial sphere Planets however are always moving and their position has to be checked regularly by observers
a condition inferior to an earlier condition; a gradual falling off from a better state
The angular distance of an astronomical body north or south of the celestial equator, taken as positive when north of the equator and negative when south The Sun moves through its declination cycle, between 23 5oN and 23 5oS, once a year, and the Moon moves through its cycle in 27 21 mean solar days The lunar declination varies from 28 5o to 18 5o over an 18 61 year period or a regression of lunar nodes cycle
the angular distance north or south of the celestial equation and measured in degrees °, minutes ' and seconds "
The declination is the coordinate in the equatorial coordinate system in the sky that is similar to latitude on Earth It ranges between -90 degrees at the southern celestial pole and +90 degrees at the northern celestial pole and is zero at the celestial equator The other equatorial coordinate is the right ascension
The angular measurement of a point according to the celestial sphere, corresponding to an angle above or below the celestial equator Equivalent to latitude in terrestrial measurements The complement to right ascension
The act or state of falling off or declining from excellence or perfection; deterioration; decay; decline
(dec): position on the celestial sphere that is the number of degrees an object is north or south of the celestial equator It is a projection of latitude lines onto the sky An object's declination is fixed with respect to the stars Varies from --90° at the SCP to 0° at the celestial equator to +90° at the NCP Vertical position of an object
One of the two angles uses to specify location on the celestial sphere Declination is like latitude, but unlike latitude, it is measured from the north pole The pole has declination 0, the equator 90 degrees, the southern celestial pole 180 degrees See right ascension and declination
The arc of the horizon, contained between the vertical plane and the prime vertical circle, if reckoned from the east or west, or between the meridian and the plane, reckoned from the north or south
(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
The angle between the magnetic and geographical meridians at any place, expressed in degrees east or west to indicate the direction of magnetic north from true north. In nautical and aeronautical navigation, the term magnetic variation is used instead of magnetic declination and the angle is termed variation of the compass or magnetic variation. Magnetic declination is not otherwise synonymous with magnetic variation which refers to regular or irregular change with time of the magnetic declination, dip, or intensityJoint Publication 1-02 U.S. Department of Defense Dictionary of Military and Associated Terms; 12 April 2001 (As Amended Through 14 April 2006)
