In astronomy, declination (abbreviated dec; symbol Î´) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle.eglecting atmospheric refraction, declination is always 0Â° at east and west points of the horizon. At the north point, it is 90Â° â | Ï |, and at the south point, â90Â° + | Ï |.
magnetic declination-the angle (at a particular location) between magnetic north and true north. magnetic variation, variation. angle-the space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians.agnetic declination. 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.
