Magsat data from the magnetically quiet days of November 5-6, 1979, were used to derive a thirteenth degree and order spherical harmonic geomagnetic field model, MGST(6/80). The model utilized both scalar and high-accuracy vector data and fit that data with root-mean-square deviations of 8.2, 6.9, 7.6 and 7.4 nT for the scalar magnitude, Br, Bθ, and Bo, respectively. The model includes the three first-order coefficients of the external field. Comparison with averaged Dst indicates that zero Dst… CONTINUE READING
