Temporal variation of the geomagnetic conjugacy in Syowa-Iceland pair
The locations of geomagnetically conjugate points of Syowa and Iceland were examined by using the geomagnetic field models with internal and external magnetic fields. A large secular excursion of the magnetic conjugate point was shown from 1960 to 1990 by tracing the IGRF geomagnetic field lines. Th...
