The angle between the two--known as the declination--varies depending on your location. It also gradually changes over time as the Earth's tectonic plates shift. If you don't adjust your compass ...

The pilot looks ahead and down, and sees the edge of the airfield at an angle of declination of 27.9 degrees. Flight Control calls back from the tower with some more details: The 350-foot tall ...

Magnetic north and geographic north align when the so-called “angle of declination”, the difference between the two norths at a particular location, is 0°. Declination is the angle in the ...

Experts from REI do a great job of explaining the basic parts of a compass and how to use them, but here is the breakdown: Magnetic declination is the angle between magnetic north and true north ...

The declination angle is the angle between an imaginary line connecting Earth-Sun centers and the equator. The declination angle varies as a function of season. It is 0 degrees at the Equinoxes ...

The magnetic poles don't line up with the geographic ones, and the difference between them is an angle called declination. As if this wasn't enough of a nuisance for navigators, the Earth's ...

Earth’s equator, projected onto the sphere, becomes the celestial equator; lines of declination in the sky ... The stars now rise at a right angle to the horizon, and all objects on the same ...
