List of Figures

  

Figure 1: The solar wind and Dst parameters during the January 9-11, 1997 magnetic cloud event with the three time intervals of interest highlighted. Note that the timing of the solar wind data acquired from the WIND satellite has been adjusted to correspond to the time at which the solar wind flow reaches the Earth. Dst is the preliminary Dst index measured by WDC-C2 for Geomagnetism, Kyoto.

  

Figure 2: POLAR satellite trajectory during the January 10 apogee pass. The trajectory is plotted in SM coordinates.

  

Figure 3: POLAR MFE residuals from IGRF (solid line) and external T96_01 fields with dynamic solar wind inputs (dotted line) for each of the three time intervals of interest. All fields are plotted in SM coordinates.

  

Figure 4: Individual contributions to the T96_01 external fields along the POLAR satellite trajectories from (a) the ring current, and (b) the variable solar wind dynamic pressure (dotted line) and variable IMF (solid line). The fields are plotted in SM coordinates and the vertical scale is smaller in 4b.

  

Figure 5: POLAR MFE residuals from the IGRF (solid line) and external T96_01 field contribution from field aligned currents only (dotted line). The fields are plotted in a field aligned coordinate system that is based upon a steady-state quiet time T96_01 model with internal IGRF fields.
