In this paper we examined the continuous motions of a near-Earth neutral lineduring the recovery phase of the 5 October 2000 substorm. Estimation was basedon the PSBL ion beam model proposed by Onsager (1991) and the Geotailobservations. Estimated distances from the Earth ranged from 20 to 60 <i>R<sub>E</sub></i>and retreated tailward at velocities of 250 and 300 km/s. This eventinitiated with the arrival of solar wind discontinuity. Simultaneousobservations of electromagnetic field and electrons indicate the existenceof earthward propagating waves associated with field-aligned currents. Basedon these observations, we suggest that the source of the PSBL ion beams wasthe retreating near-Earth neutral line formed by the compression ofthe magnetosphere. Two scenarios of near-Earth neutral line motion in the taildynamics are also proposed. One is the formation of plural neutral lines tocreate a long plasmoid. The other is the oscillation of one neutral linebetween the near-Earth region and the mid-tail stagnant plasmoid
