The authors describe in detail a four hour period on Dec 17, 1992, of cusp/cleft region observations, made in conjunction with the occurance of a transient auroral event. There was an IMF directional discontinuity where the fields changed from positive IMF B{sub y} (B{sub z}{much_lt}0) to large negative B{sub y} (B{sub z}>0) in conjunction with a change in convection direction in the cusp region. They present data from satellite observations, in addition to ground based data collected over an array of stations in Greenland and Svalbard. They view this as a first step toward an effort to correlate responses in the ionosphere to different solar wind and interplantetary magnetic field conditions. They analyze this data in terms of the array of different conditions which was exhibited in the ionosphere over this four hour period.
