520 | _aThe main electron density trough in the topside ionosphere is investigated using ISIS 2 topside sounder data, DMSP auroral images and ground-based observations. A "base-level" ionospheric trough is characterized with the aid of ISIS 2 electron densities obtained in December 1971 under an optimun set of geophysical conditions, namely midwinter, local midnight and very quiet magnetospheric intervals. The statistical positions of the equatorward and poleward walls of the trough are examined in relation to the plasmapause and various auroral boundaries, respectively. | ||
