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.

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 …

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.

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 …

Declination is essentially the difference between true north and magnetic north.

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 …

Declination, the difference between magnetic north and true north, is key to accurate navigation. Learn how to adjust for it on a compass.

The magnetic declination calculator tells you the difference between true north and magnetic north at your location. We use magnetic declination for many applications, including navigation, …

Declination involves the measurement of the position of such objects as being north or south of the celestial equator. Those north of the celestial equator are measured in positive 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 …
