Declination: How To Interpret Results Geomag - Models@noaa - Gov

The document provides the magnetic declination for a location at 34.54590° S, 60.93060° W at an elevation of 0 km. The declination is reported as 6.65° W, changing by 0.17° W per year, with an uncertainty of 0.39°. Magnetic declination is defined as the angle between true north and magnetic north as indicated on a compass.

Declination

Date 2017-04-26

Latitude 34.54590 S

Longitude 60.93060 W

Elevation 0.0 km GPS

Model Used WMM2015

Declination 6.65 W changing by

0.17 W per year

Uncertainty 0.39

Compass shows the approximate bearing of the


magnetic north (MN)

Magnetic declination is the angle between true north and the horizontal trace of the
local magnetic field. In general, the present day field models such as the IGRF and
World Magnetic Model (WMM) are accurate to within 30 minutes of arc for the
declination. However, local anomalies exceeding 10 degrees, although rare, do exist.
