Magnetic declination, sometimes called magnetic variation, is the angle between magnetic north and true north. Declination is positive east of true north and negative when west.

In astronomy, declination (abbreviated dec; symbol δ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle.

The meaning of DECLINATION is angular distance north or south from the celestial equator measured along a great circle passing through the celestial poles. How to use declination in a …

What is declination? At most places on the Earth's surface, the compass doesn't point exactly toward geographic north. The deviation of the compass from true north is an angle called …

Magnetic declination is calculated using the World Magnetic Model WMM2025.

This difference between where your compass points (Magnetic North) and the real north on a map (True North), measured as an angle in degrees, is called magnetic declination.

Declination is defined as the position of the sun at noon (solar time) north and south of the celestial equator (measured in degrees).

Declination, in astronomy, the angular distance of a body north or south of the celestial equator. Declination and right ascension, an east-west coordinate, together define the position of an …

All holes were drilled at between approximately -45 to -50 degree declinations. The second drill hole was drilled at a declination of -75 degrees. He was as baffled as I about the FBI's …

Magnetic declination, or declination, is the difference between the true north reading from the map and the magnetic north reading from a compass. When a compass is used in combination with …
