• The electron precipitation in the northern and southern conjugate regions, observed by the DMSP-F2,F3 and F4 satellites, is examined. The high energy auroral electron precipitation region (the average energy higher than 500eV and the number flux greater than (10)^7 electrons/(cm)^2・s・sr) shows similar electron precipitation patterns in the conjugate regions, regardless of the degree of geomagnetic activity. On the other hand, the width and structure of the low energy auroral electron precipitation regions (the average energy lower than 500eV and the number flux greater than (10)^7 electrons/(cm)^2・s・sr) during quiet periods are some-what different in the opposite hemispheres. Some of the differences seem to be controlled by the interplanetary magnetic field.
