DC electric field at at 140 km altitude measured by EISCAT 140 km and equlpotential contours at the location A - G and those (dash-dotted curves) at 140 km derived from CAESAR electric field altitude, data along the trajectory. are mapped down the Earth magnetic field lines to the altitude of 140 km. (The foot points of these arrows represent the projected trajectory of the payloadj The full dots are time marks every 100 s flight time. The agreement between both data sets south of the precipitation region is evident but there are discrepancies close and within that region. At the southern boundary there is a well defined clockwise vortex (between the EISCAT positions E and P and the projected trajectory at about 450 s flight time), and at the northern boundary a counter clockwise vortex is indicated by the CAESAR data. Figure 3 is the plot of the electric fields corresponding to Pig.2. The CAESAR electric field is mapped down the Earth magnetic fieldlines to the altitude of 140 km and the EISCAT electric fields are derived from measured geogt. Longitude 12 13 IA 91 Qeogz. Latitude
