| Popis: | The concepts of geomagnetic time and position of a station on Earth are reviewed on the basis of the centred dipole, and the eccentric dipole, magnetic field approximations. Equations are presented from which the centred dipole coordinates can be computed as a special case of the eccentric dipole coordinates. It is also shown that several aspects relating to geomagnetism appear to vary nearly linearly with time and are well represented by linear regression equations which can significantly simplify subsequent computations. Sufficient information is included so that magnetic time and position for any station on Earth may be calculated. Sample results are presented which specifically relate to Scott Base, Antarctica. |
