 | | Until the last update it worked for almost fourty years based on photographic method for monitoring geomagnetic variations. |
 | | MOP posseses for the absolute measurements one Askania Declinometer for D, one QHM1056 for Horizontal Intensity, one Helmholtz Coil System for the measurements of H and Z components-not in use-and a MP-2 proton magnetometer for the measurement of F, total field intensity. |
 | | The monitoring of the geomagnetic field variations is done with a fluxgate coil system constructed by the Danish Meteorological Institute. |
