On the origin of electric fields in the plasmasphere
Whistler data recorded continuously at Sanae, Antarctica (L=4) over a 24 hour period of quiet magnetic conditions (average Kp=1) have been analysed to obtain plasma convection patterns. A duskside plasmaspheric bulge is present, centered on 1700 UT. The westward electric fields determined for this b...
