Abstract:

The geomagnetic potential IGRF 1965.0 is converted into the spherical coordinates of an optimally offset and inclined dipole by means of a least-squares fit to the transformed Schmidt coefficients. Time derivatives of the resulting spherical-harmonic expansion coefficients are obtained by taking symmetric first differences 1966.0 vs 1964.0. Author
